Means for Solving the Problems

[0006] The composition according to an embodiment of the present invention includes the following (A) to (C). (A) 0.1% by mass to 20.0% by mass of an N-vinyl lactam-based polymer (component (a)), (B) At least one (component b) selected from the group consisting of lower alcohols, higher alcohols, polyhydric alcohols, organic acids, and fatty acids, in an amount of 0.01% to 99.89% by mass, (C) At least one (component c) selected from the group consisting of silicone oils, ester oils, and hydrocarbon oils, in an amount of 0.01% to 99.89% by mass.

Advantages of the Invention

[0021] According to the present invention, it is possible to provide a composition in which various oils are thickened and which has excellent thickening properties. Further, according to the present invention, in some cases, it is possible to provide a composition in which various oils are thickened, which has excellent thickening properties, further excellent film-forming properties, and imparts a coherence to the hair. Thickening the oil has the advantages of improving emulsion stability, improving stability over time, and providing a thick coating feel. Coherent hair refers to a state in which there are few gaps between the hairs when the hairs are bundled together and there is a straight and neat sense of unity. When the hair has many waves and sideburns, gaps are formed between the hairs, resulting in unruly hair. The coherence of the hair has the advantage that the hair is easily aligned after drying and a light and comfortable feeling remains. A composition containing an N-vinyl lactam-based polymer can assist in adhering to the hair, making it difficult to form gaps, and can impart coherence to the hair.

Modes for Carrying Out the Invention

[0022] When the term "weight" is used in this specification, it may be read as "mass", which is a SI unit commonly used to indicate weight.

[0023] When the content ratio of a specific component is expressed as "substantially 100% by mass" in this specification, it means excluding forms in which another component is actively added or actively used in combination to exhibit effects other than the effects attributed to the specific component. For example, the inclusion of impurities unavoidably mixed in during the manufacturing process or the like is allowed as long as the effects of the present invention are not impaired.

[0024] In this specification, "IOB" is an abbreviation of Inorganic Organic Balance, and is a value obtained as the ratio (IV / OV = IOB) of specific characteristic values, namely, the Organic Value (OV) and the Inorganic Value (IV), based on the organic concept map (see Fujita Akira, "Prediction of Organic Compounds and Organic Concept Maps," Chemistry Field, VOL.11, No.10 (1957) 719-715; Fujita Akira, "Systematic Organic Qualitative Analysis," Kazama Shobo (1974); Koda Yoshio, "Organic Concept Maps - Basics and Applications," Sankyo Publishing (1984), etc.). The organic concept map is widely used particularly in the fields of environmental chemistry and pharmacochemistry as it can well represent the properties of relatively complex interacting organic substances. In the organic concept map, regarding the physicochemical properties of compounds, the degree of physical properties mainly due to Van Der Waals force is called "organic property," and the degree of physical properties mainly due to electrical affinity is called "inorganic property," and the physical properties of compounds are grasped by combining these. For these "organic property" and "inorganic property," specific characteristic values, namely, the Organic Value (OV) and the Inorganic Value (IV), are assigned to individual compounds, and by "locating" a large number of compounds in the substance field, various trends can be confirmed for each region. Conversely, this indicates that for an unknown compound, if the organic value and inorganic value can be obtained from its structural formula, a prediction of its properties can be obtained. Regarding the organic concept map, typically, it is described on the homepage of Nihon Emulsion Co., Ltd. (at the time of filing this application, https: / / www.nihon-emulsion.co.jp / tech / organic.html).

[0025] ≪Composition≫ The composition according to an embodiment of the present invention is typically a thickening composition. The "thickening composition" refers to a composition having thickening properties. Whether it has thickening properties may be determined, for example, according to the generally conventional criteria for thickening properties. In this specification, those that receive an evaluation of ○ or △ in the evaluation of thickening properties described later are considered to have thickening properties.

[0026] The composition according to an embodiment of the present invention can be used in any suitable drug as long as the effects of the present invention are not impaired. Examples of such drugs include, for example, cosmetics, fragrances, flavoring agents, deodorants, pharmaceuticals, insect repellents, insecticides, agricultural chemicals, etc., and typically, cosmetics are mentioned. Examples of such cosmetics include, for example, hair styling agents.

[0027] That is, the composition according to one embodiment of the present invention is typically a thickening composition for cosmetics, and examples thereof include a thickening composition for hair styling agents.

[0028] The composition according to an embodiment of the present invention contains the following (A) to (C). (A) 0.1% by mass to 20.0% by mass of an N-vinyl lactam-based polymer (component a). (B) 0.01% by mass to 99.89% by mass of at least one selected from the group consisting of lower alcohols, higher alcohols, polyhydric alcohols, organic acids, and fatty acids (component b). (C) 0.01% by mass to 99.89% by mass of at least one selected from the group consisting of silicone oils, ester oils, and hydrocarbon oils (component c).

[0029] By containing the above (A) to (C), the composition according to an embodiment of the present invention can have excellent thickening properties and become a composition in which various oil agents are thickened.

[0030] <Component a> The composition according to an embodiment of the present invention contains 0.1% by mass to 20.0% by mass of an N-vinyl lactam-based polymer (component a).

[0031] Component a may be only one kind or two or more kinds.

[0032] As described above, the content ratio of Component a in the composition is 0.1% by mass to 20.0% by mass, preferably 0.5% by mass to 15.0% by mass, more preferably 1.0% by mass to 10.0% by mass, still more preferably 2.0% by mass to 8.0% by mass, particularly preferably 3.0% by mass to 7.0% by mass, and most preferably 4.0% by mass to 6.0% by mass. If the content ratio of Component a in the composition is outside the above range, there is a possibility that a composition in which various oil agents having excellent thickening properties are thickened cannot be provided.

[0033] Also, when seeking film-forming properties, the content ratio of Component a in the composition is 0.1% by mass to 20.0% by mass, preferably 0.2% by mass to 10.0% by mass, more preferably 0.3% by mass to 8.0% by mass, still more preferably 0.4% by mass to 7.0% by mass, particularly preferably 0.5% by mass to 6.0% by mass, and most preferably 0.6% by mass to 5.0% by mass. If the content ratio of Component a in the composition is outside the above range, there is a possibility that a composition in which various oil agents having excellent thickening properties are thickened and further having excellent film-forming properties cannot be provided.

[0034] In terms of more effectively expressing the effects of the present invention, Component a preferably contains a structural unit derived from an N-vinyl lactam monomer in an amount of 50 mol% to 100 mol%, more preferably 60 mol% to 100 mol%, still more preferably 70 mol% to 100 mol% based on 100 mol% of the structural units derived from all monomers.

[0035] The structural unit derived from the N-vinyl lactam monomer contained in Component a may be only one kind or two or more kinds.

[0036] Typical examples of the structural unit derived from the N-vinyl lactam monomer include the structural unit represented by the general formula (1).

[0037]

Chemical formula

[0038] In general formula (1), R represents a hydrogen atom or a methyl group.

[0039] In general formula (1), m represents an integer of 1 to 3.

[0040] In this specification, the structural unit derived from a monomer is a structural unit having the same structure as the structure formed by the polymerization of the monomer. However, the structural unit derived from a monomer is not limited to the structural unit actually formed by the polymerization of the monomer, and is included in the structural unit derived from the monomer as long as it has the same structure as the structure formed by the polymerization of the monomer.

[0041] Typical examples of the monomer capable of forming a structural unit derived from an N-vinyl lactam monomer include N-vinyl lactam monomers represented by general formula (2).

[0042]

Chemical formula

[0043] In general formula (2), R represents a hydrogen atom or a methyl group.

[0044] In general formula (2), m represents an integer of 1 to 3.

[0045] Examples of the monomer represented by general formula (2) include N-vinyl pyrrolidone, N-vinyl piperidone, N-vinyl caprolactam, and the like. In terms of more effectively expressing the effects of the present invention, the monomer represented by general formula (2) is preferably N-vinyl pyrrolidone.

[0046] Component a may have other structural units other than the structural unit derived from the N-vinyl lactam monomer. The other structural units are structural units derived from other monomers other than the N-vinyl lactam monomer.

[0047] There may be only one type of the other structural units, or two or more types. There may be only one type of the other monomers, or two or more types.

[0048] As other monomers, any appropriate monomer can be employed as long as it can copolymerize with the N-vinyl lactam-based monomer, without impairing the effects of the present invention. Examples of such other monomers include, 1) (Meth)acrylic acid esters such as methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, cyclohexyl (meth)acrylate; 2) Hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, 3-(meth)allyloxy-1,2-dihydroxypropane, (meth)allyl alcohol, isoprenol, and unsaturated alcohols obtained by adding alkylene oxide to these hydroxyl groups, 3) (Meth)acrylamide derivatives such as (meth)acrylamide, N-methyl (meth)acrylamide, N-ethyl (meth)acrylamide, N,N-dimethyl (meth)acrylamide; 4) Basic unsaturated monomers such as dimethylaminoethyl (meth)acrylate, dimethylaminoethyl (meth)acrylamide, vinylpyridine, vinylimidazole, and salts or quaternized products thereof; 5) Vinylamides such as vinylformamide, vinylacetamide, vinyl oxazolidone; 6) Carboxyl group-containing unsaturated monomers such as (meth)acrylic acid, itaconic acid, maleic acid, fumaric acid, and salts thereof; 7) Unsaturated anhydrides such as maleic anhydride, itaconic anhydride; 8) Vinyl esters such as vinyl acetate, vinyl propionate; 9) Vinyl ethylene carbonate and its derivatives; 10) Styrene and its derivatives; 11) 2-Sulfoethyl (meth)acrylate and its derivatives; 12) Vinyl sulfonic acids and their derivatives such as 3-allyloxy-2-hydroxypropanesulfonic acid, (meth)allyl sulfonic acid, isoprene sulfonic acid, and salts thereof; 13) Vinyl ethers such as methyl vinyl ether, ethyl vinyl ether, butyl vinyl ether; 14) Olefins such as ethylene, propylene, octene, butadiene; etc. are exemplified.

[0049] As the alkylene oxide in the case of the other monomers in the above 2), an alkylene oxide having 1 to 20 carbon atoms is preferable, and an alkylene oxide having 1 to 4 carbon atoms is more preferable. In terms of being able to more effectively exhibit the effects of the present invention, as the alkylene oxide, at least one selected from the group consisting of ethylene oxide and propylene oxide is preferable.

[0050] As the number of moles of addition of the alkylene oxide in the case of the other monomers in the above 2), 0 to 50 moles is preferable, and 0 to 20 moles is more preferable, per 1 mole of the compound in the above 2).

[0051] Among the above 1) to 14), as the other monomers, from the viewpoint of copolymerizability with N-vinyl lactam-based monomers, etc., preferably 1) to 9), more preferably 1) to 6).

[0052] The content ratio of the structural unit derived from the other monomer in the a component is preferably 0 mol% to 50 mol%, preferably 0 mol% to 40 mol%, more preferably 0 mol% to 30 mol%, based on 100 mol% of the structural unit derived from all monomers, in terms of being able to more effectively exhibit the effects of the present invention.

[0053] The a component preferably has a crosslinked structure. By the a component having a crosslinked structure, the effects of the present invention can be more effectively exhibited.

[0054] The crosslinked structure is at least one selected from the group consisting of a structure derived from a crosslinking agent having at least two polymerizable double bond groups per molecule, and a structure formed by the reaction of the main chain or side chains of the polymer.

[0055] As the crosslinking agent, any appropriate crosslinking agent can be employed as long as the effects of the present invention are not impaired. Examples of such crosslinking agents include N,N'-methylenebis(meth)acrylamide, (poly)ethylene glycol di(meth)acrylate, (poly)propylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, trimethylolpropane di(meth)acrylate, glycerin tri(meth)acrylate, glycerin acrylate methacrylate, ethylene oxide-modified trimethylolpropane tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, pentaerythritol tri(meth)acrylate, dipentaerythritol hexa(meth)acrylate, triallyl cyanurate (triallyl cyanate), triallyl isocyanurate, triallyl phosphate, triallylamine, pentaerythritol tetraallyl ether, pentaerythritol triallyl ether, pentaerythritol diallyl ether, poly(meth)allyloxyalkane, divinylbenzene, divinyltoluene, divinylxylene, divinylnaphthalene, divinyl ether, divinyl ketone, trivinylbenzene, tolylene diisocyanate, hexamethylene diisocyanate, diallyl carbonate, 1,3-bis(allyloxy)-2-propanol, divinylethyleneurea, 1,4-butylene bis(N-vinylamide), and (di, tri, tetra, penta, hexa, hepta, octa)allyl sucrose, etc.

[0056] Among the above crosslinking agents, since the remaining N-vinyl lactam-based monomers and the soluble components (polymer components that are not crosslinked and are soluble in water) tend to decrease, it is preferable to use a compound having two or more allyl groups. Specifically, pentaerythritol (di, tri, tetra)(meth)allyl ether, triallyl isocyanurate, triallyl phosphate, triallylamine, diallyl carbonate, 1,4-butylene bis(N-vinylamide), and (di, tri, tetra, penta, hexa, hepta, octa)allyl sucrose are preferable, and pentaerythritol (di, tri, tetra)allyl ether and (di, tri, tetra, penta, hexa, hepta, octa)allyl sucrose are more preferable. Pentaerythritol (di, tri, tetra)allyl ether and (di, tri, tetra, penta, hexa, hepta, octa)allyl sucrose have higher safety, and thus the crosslinked polymer obtained by adopting such a crosslinking agent can be more suitably used for cosmetic applications.

[0057] The crosslinking agent may be only one kind or two or more kinds.

[0058] When the a component has a crosslinked structure, the content ratio of the structural units derived from the crosslinking agent in the a component is preferably 0.001 mol% to 10 mol%, more preferably 0.005 mol% to 5 mol%, still more preferably 0.01 mol% to 5 mol%, particularly preferably 0.01 mol% to 1 mol%, and most preferably 0.05 mol% to 0.8 mol% with respect to 100 mol% of the structural units derived from all monomers in terms of more effectively expressing the effects of the present invention.

[0059] Although the crosslinking agent has a polymerizable double bond group, in this specification, for the sake of clarity of the composition, the crosslinking agent shall not be treated as a monomer. That is, the crosslinking agent is not included in the "total monomers".

[0060] The method for producing component a preferably includes a step of polymerizing a monomer component containing an N-vinyl lactam-based monomer. As such a polymerization reaction method, any appropriate polymerization method can be adopted as long as the effects of the present invention are not impaired. Examples of such polymerization methods include bulk polymerization method, solution polymerization method, emulsion polymerization method, suspension polymerization method, precipitation polymerization method, and the like. Among these polymerization methods, the solution polymerization method and the precipitation polymerization method are preferred, and the precipitation polymerization method is more preferred, in terms of being able to more effectively exhibit the effects of the present invention.

[0061] <Manufacturing method using precipitation polymerization method> In the precipitation polymerization method, typically, it includes a dropping step of separately dropping a monomer component containing an N-vinyl lactam-based monomer and a polymerization initiator into a reaction medium.

[0062] The amount of the polymerization initiator in the initial reaction medium before the dropping step is preferably 30% by mass or less, more preferably 20% by mass or less, still more preferably 10% by mass or less, and particularly preferably 0% to 5% by mass, based on the total amount of the polymerization initiator used in the reaction.

[0063] In the dropping step, preferably, the polymerization initiator is dropped over a time longer than the dropping time of the monomer component to obtain a polymer as an aggregate. This aggregate preferably includes spherical objects, and examples of such spherical objects include complete spherical objects, substantially spherical objects, and substantially elliptical objects in plan view.

[0064] The precipitation polymerization method is a polymerization method in a polymerization system where the monomer component is compatible and soluble with the polymerization solvent, but the generated polymer is insoluble in the polymerization solvent. In this polymerization method, as the polymerization reaction proceeds, the generated polymer precipitates. The precipitated polymer is swollen with the monomer component, and the polymerization reaction proceeds in the solvent and in the vicinity of the polymer, respectively. In this case, a polymerization initiator is used, and such a polymerization initiator is preferably soluble in both the polymerization solvent and the monomer component.

[0065] In the dropping step, as a method of separately dropping a monomer component containing an N-vinyl lactam monomer and a polymerization initiator into a reaction medium, for example, the monomer component containing the N-vinyl lactam monomer and the polymerization initiator may be put into separate dropping funnels and separately dropped into a reaction vessel containing an initial reaction medium. The monomer component containing the N-vinyl lactam monomer and the polymerization initiator may each be a mixed solution with a solvent.

[0066] In the precipitation polymerization method, a solvent is used as the reaction medium. Examples of the solvent include hydrocarbon solvents such as heptane and cyclohexane.

[0067] Examples of the initial reaction medium before the dropping step include a solvent or a solvent to which a polymerization initiator in the above-mentioned range is added. The amount of the monomer component in the initial reaction medium is preferably 30% by mass or less, more preferably 20% by mass or less, still more preferably 10% by mass or less, and particularly preferably 0% by mass to 5% by mass with respect to the total amount of the monomer component.

[0068] The dropping time of the monomer component into the initial reaction medium is preferably 0.5 hour to 10.0 hours. Also, the dropping time of the polymerization initiator into the initial reaction medium is preferably longer than the dropping time of the monomer component, and more preferably 1.0 hour to 20 hours. The dropping time of the polymerization initiator into the initial reaction medium is preferably 1.10 times to 3.00 times, more preferably 1.15 times to 2.50 times, and still more preferably 1.20 times to 2.00 times the dropping time of the monomer component.

[0069] The polymerization temperature when performing the precipitation polymerization method is preferably +15°C or higher and +30°C or lower with respect to the 10-hour half-life temperature of the polymerization initiator. The polymerization temperature is the temperature of the reaction solution while the monomer component is being dropped, and when it varies during the reaction, it is taken as the intermediate value between the maximum temperature and the minimum temperature. The 10-hour half-life temperature is the temperature at which the concentration of the polymerization initiator becomes 1 / 2 of the initial value 10 hours after the start of the reaction, and is generally used as a criterion for the selection of the polymerization initiator.

[0070] When the polymerization initiator is added all at once initially, the concentration of initiating radicals in the reaction system decreases with the passage of time. On the other hand, when the polymerization initiator is dropped into the reaction solution at an appropriate temperature, the concentration of initiating radicals is kept constant, monomer consumption is stable, and agglomeration of the polymer and adhesion to the reactor wall and stirring blades can be suppressed. The polymerization initiator will be described later.

[0071] As the 10-hour half-life temperature of the polymerization initiator, for example, the values published by the manufacturer can be used. In the case of organic peroxide initiators, for example, they are published by NOF Corporation.

Also, the 10-hour half-life temperatures of similar polymerization initiators have been disclosed by Arkema Yoshitomi Co., Ltd.

[0072] Regarding the 10-hour half-life temperatures of azo-based polymerization initiators, for example, they have been published by Fuji Film Wako Pure Chemical Industries, Ltd. It is 65 °C for 2,2-azobis(isobutyronitrile), 30 °C for 2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile), 51 °C for 2,2'-azobis(2,4-dimethylvaleronitrile), 66 °C for dimethyl 2,2'-azobis(2-methylpropionate), 67 °C for 2,2'-azobis(2-methylbutyronitrile), 88 °C for 1,1'-azobis(cyclohexane-1-carbonitrile), 110 °C for 2,2'-azobis(N-butyl-2-methylpropionamide), and 73 °C for dimethyl 1,1-azobis(1-cyclohexanecarboxylate).

[0073] In the sedimentation polymerization method, any suitable polymerization initiator can be employed as long as the effects of the present invention are not impaired. Examples of such polymerization initiators include, for example, persulfates, hydrogen peroxide, organic peroxides, azo compounds, etc., and preferably, organic peroxides and azo compounds. As the polymerization initiator, a redox initiator that generates radicals by combining an oxidizing agent and a reducing agent can also be used.

[0075] Examples of azo compounds include 2,2-azobis(isobutyronitrile), 2,2’-azobis(4-methoxy-2,4-dimethylvaleronitrile), 2,2’-azobis(2,4-dimethylvaleronitrile), dimethyl-2,2’-azobis(2-methylpropionate), 2,2’-azobis(2-methylbutyronitrile), 1,1’-azobis(cyclohexane-1-carbonitrile), 2,2’-azobis(N-butyl-2-methylpropionamide, dimethyl-1,1-azobis(1-cyclohexanecarboxylate), etc.

[0076] The amount of the polymerization initiator used is preferably 0.01 g to 10 g, more preferably 0.05 g to 7 g, and even more preferably 0.1 g to 5 g, per 1 mol of the total amount of all monomers and crosslinking agents. By using the polymerization initiator in such an amount, the ratio of unreacted monomers and crosslinking agents contained in the resulting polymer can be sufficiently reduced.

[0077] As the reaction vessel for carrying out the polymerization step, any appropriate reaction vessel made of any material can be adopted as long as it can carry out the polymerization step. Examples of such a reaction vessel include reaction vessels made of materials such as stainless steel. By carrying out the polymerization reaction using such a reaction vessel made of a material with good heat transfer, the polymerization reaction can proceed sufficiently, and the content of unreacted monomers and crosslinking agents contained in the resulting polymer can be reduced. It is also preferable to use a reaction vessel made of a material that does not elute iron, such as polypropylene. By using such a reaction vessel made of such a material, the content of iron contained in the resulting polymer can be reduced.

[0078] When carrying out the polymerization reaction in the polymerization process, the shape of the stirring blade can adopt any appropriate shape as long as the effects of the present invention are not impaired. Examples of such shapes include paddle type, multi-stage paddle type, inclined paddle type, anchor type, propeller type, combinations thereof, and Max Blend type.

[0079] By carrying out the polymerization by the precipitation polymerization method, the control of the polymerization becomes easy. According to the precipitation polymerization method, a polymer containing spherical objects in which very small primary particles are gently aggregated is preferably obtained. These spherical objects are heavier than the influence of static electricity and air flow, are difficult to scatter powder, are easy to handle, and can be very easily pulverized. Therefore, it is possible to exhibit an excellent effect that a special pulverizer is not required for pulverization. Further, when the above-mentioned aggregated spherical objects are put into a solution, they quickly become primary particles and disperse, and a uniform dispersion or gel-like substance can be obtained in a short time. Similarly, for the spherical objects after pulverization, by putting them into a solution, they quickly become primary particles and disperse, and a uniform dispersion or gel-like substance can be obtained in a short time.

[0080] The polymer obtained by the precipitation polymerization method preferably becomes spherical objects of several hundred μm. The size of such spherical objects is preferably more than 100 μm and 2000 μm, more preferably 200 μm to 1500 μm, and still more preferably 300 μm to 1000 μm.

[0081] The polymer obtained by the precipitation polymerization method, preferably spherical objects, is an aggregate of amorphous primary particles. The particle diameter of such amorphous primary particles is preferably 2 μm or less, more preferably 10 nm to 2000 nm, and still more preferably 20 nm to 1000 nm.

[0082] In the precipitation polymerization method, in addition to the polymerization process, any other appropriate process may be included as long as the effects of the present invention are not impaired. Examples of such other processes include a drying process, a pulverization process, a classification process, a granulation process, a post-crosslinking process, and the like.

[0083] In the precipitation polymerization method, it is preferable to provide a drying step. The drying step refers to an operation for increasing the solid content, and usually, the ratio of the solid content to the mass of the entire polymer is increased compared to that before drying. The drying may be performed simultaneously with a part of the polymerization, or drying during polymerization and drying after polymerization may be used in combination. Preferably, a drying step is provided after polymerization, in which the polymerization is dried using a drying device.

[0084] The drying step is preferably carried out in the range of 80°C to 250°C for 50% or more of the total drying step time, and preferably throughout substantially the entire drying step. By carrying out the drying step in this manner, various physical properties of the polymer can be further improved. The drying temperature is determined by the heat medium temperature, but when it cannot be determined by the heat medium temperature such as microwaves, it is determined by the material temperature. As the drying method, any appropriate drying method can be adopted as long as the drying temperature is within the above range and does not impair the effects of the present invention. Examples of such drying methods include hot air drying, windless drying, reduced pressure drying, infrared drying, and microwave drying. Among these drying methods, it is preferable to use hot air drying and reduced pressure drying. When hot air drying is used, the drying air volume is preferably 0.01 m / sec to 10 m / sec, more preferably 0.1 m / sec to 5 m / sec. The drying temperature range is more preferably 110°C to 220°C, and even more preferably 120°C to 200°C. The drying may be performed at a constant temperature or at a variable temperature, but it is preferable that substantially all of the drying steps are performed within the above temperature range.

[0085] In order to more effectively exhibit the effects of the present invention, it is preferable to provide a pulverization step in the precipitation polymerization method. The pulverization step is preferably carried out using a pulverizer. When the precipitation polymerization method includes a drying step, the pulverization step may be carried out before, during, or after the drying step, and is preferably carried out after the drying step.

[0086] As described above, according to the precipitation polymerization method, a polymer containing spherical objects in which very small primary particles are gently aggregated can be preferably obtained, and since it can be very easily pulverized, it can exhibit an excellent effect that a special pulverizer is not required for pulverization. Therefore, a simple pulverizer can be employed as the pulverizer. Examples of such a pulverizer include roll-type pulverizers such as roll mills, hammer-type pulverizers such as hammer mills, impact pulverizers, cutter mills, turbo grinders, ball mills, flash mills, jet mills, and the like. Among these, when controlling the particle size distribution more, it is preferable to use a roll mill. In order to control the particle size distribution, it may be pulverized continuously two or more times, or may be pulverized continuously three or more times. Also, when pulverizing two or more times, each pulverizer may be the same or different. It is also possible to use a combination of different types of pulverizers.

[0087] In order to control the polymer obtained by the precipitation polymerization method to a specific particle size distribution, a classification step or a granulation step may be provided. In the classification step, a sieve with a specific mesh size may be used. As the classifier used for classification with a sieve, any appropriate classifier can be employed as long as the effects of the present invention are not impaired. Examples of such a classifier include vibrating sieves (unbalanced weight drive type, resonance type, vibration motor type, electromagnetic type, circular vibration type, etc.), in-plane motion sieves (horizontal motion type, horizontal circular-linear motion type, three-dimensional circular motion type, etc.), movable mesh sieves, forced stirring sieves, mesh surface vibration sieves, air sieves, sonic sieves, and the like.

[0088] <Manufacturing method using solution polymerization method> In the solution polymerization method, a solvent is preferably used. Examples of the solvent include at least one selected from the group consisting of water and alcohol. Examples of the alcohol include methyl alcohol, ethyl alcohol, isopropyl alcohol, n-butyl alcohol, diethylene glycol, and the like. When using a solvent, the concentration of the monomer component in the solution is preferably 20% by mass or more and 80% by mass or less. If the concentration of the monomer component in the solution is less than 20% by mass, it may be difficult to obtain a polymer, or even if obtained, it may be difficult to crush it after polymerization. In addition, a long time is required for drying after the polymerization reaction, and there is a risk that the polymer will deteriorate during drying. On the other hand, if the concentration of the monomer component in the solution exceeds 80% by mass, it becomes difficult to control the polymerization, and the residual monomer may increase.

[0089] In the solution polymerization method, as reaction conditions such as reaction temperature and pressure in the polymerization reaction, any appropriate conditions can be adopted as long as the effects of the present invention are not impaired. Such conditions include, for example, the reaction temperature is preferably 20 to 150 °C, and the pressure in the reaction system is preferably normal pressure or reduced pressure.

[0090] In the solution polymerization method, as a means for initiating the polymerization of the monomer component, any appropriate means can be adopted as long as the effects of the present invention are not impaired. Such means include, for example, a method of adding a polymerization initiator, a method of irradiating with UV, a method of applying heat, a method of irradiating with light in the presence of a photoinitiator, and the like.

[0091] As the polymerization initiator, any appropriate polymerization initiator can be employed as long as the effects of the present invention are not impaired. Examples of such polymerization initiators include peroxides such as hydrogen peroxide and t-butyl hydroperoxide; azo compounds such as 2-(carbamoylazo)isobutyronitrile, 2,2'-azobis(2-amidinopropane) dihydrochloride, 2,2'-azobis(2-methyl-N-phenylpropionamidine) dihydrochloride, 2,2'-azobis[2-(N-allylamidinopropane)] dihydrochloride, 2,2'-azobis[2-(5-hydroxy-3,4,5,6-tetrahydropyrimidin-2-yl)propane] dihydrochloride, 2,2'-azobis[2-(2-imidazolin-2-yl)propane], 2,2'-azobis[2-(2-imidazolin-2-yl)propane] dihydrochloride, 2,2'-azobis[2-(2-imidazolin-2-yl)propane] disulfate hydrate, 4,4'-azobis(4-cyanopentanoic acid), 2,2'-azobis[N-(2-carboxyethyl)-2-methylpropionamidine] n-hydrate, 2,2'-azobis[2-methyl-N-(2-hydroxyethyl)propionamide]; persulfates such as potassium persulfate, ammonium persulfate, and sodium persulfate; redox initiators that generate radicals by combining an oxidizing agent and a reducing agent, such as ascorbic acid and hydrogen peroxide, sodium sulfoxylate and t-butyl hydroperoxide, and persulfate and metal salts; and the like. The polymerization initiator may be only one kind or two or more kinds.

[0092] As the amount of the polymerization initiator used, any appropriate amount can be adopted as long as the effects of the present invention are not impaired. Examples of such amounts include, for example, 0.002% by mass to 15% by mass, preferably 0.01% by mass to 5% by mass, based on the total of 100% by mass of the total monomers (the total of the N-vinyl lactam-based monomer and other monomers) and the crosslinking agent.

[0093] In the solution polymerization method, a basic pH regulator may be used for purposes such as accelerating the polymerization reaction and preventing hydrolysis of the N-vinyl lactam-based monomer. The addition of the basic pH regulator can be carried out by any appropriate method within a range that does not impair the effects of the present invention. For example, it may be charged into the system from the initial stage of polymerization, or sequentially added during polymerization. Specific examples of the basic pH regulator include ammonia; aliphatic amines such as monoethanolamine, diethanolamine, and triethanolamine; aromatic amines such as aniline; hydroxides of alkali metals such as sodium hydroxide and potassium hydroxide; and the like. Among these, ammonia, monoethanolamine, diethanolamine, sodium hydroxide, and potassium hydroxide are preferred. The basic pH regulator may be only one kind or two or more kinds. When using a basic pH regulator, any appropriate amount can be adopted as long as the effects of the present invention are not impaired. Such an amount is preferably used so that the solution during polymerization is in a pH range of preferably 5 to 10, more preferably 7 to 9.

[0094] In the solution polymerization method, a transition metal salt may be used for purposes such as accelerating the polymerization reaction. Specific examples of the transition metal salt include carboxylates and chlorides of copper, iron, cobalt, nickel, and the like. The transition metal salt may be only one kind or two or more kinds. When using a transition metal salt, any appropriate amount can be adopted as long as the effects of the present invention are not impaired. Such an amount is preferably 0.1 ppb to 20,000 ppb, more preferably 1 ppb to 5,000 ppb, by mass ratio with respect to the monomer component.

[0095] In the solution polymerization method, any appropriate other additives may be used within a range that does not impair the effects of the present invention. Examples of such other additives include chain transfer agents, buffers, and the like.

[0096] When using a crosslinking agent in the solution polymerization method, a crosslinked polymer may be obtained by a method of polymerizing a monomer component in the presence of the crosslinking agent, or a crosslinked polymer may be obtained by a method of performing a crosslinking treatment after polymerizing the monomer component. Preferably, a crosslinked polymer is obtained by a method of polymerizing a monomer component in the presence of a crosslinking agent. Examples of the method of performing a crosslinking treatment after polymerization include (i) a method of irradiating the polymer with UV, γ-rays, or electron beams, (ii) a method of adding heat to the polymer to cause self-crosslinking, (iii) a method of adding a radical generator to the polymer and then adding heat to cause self-crosslinking, (iv) a method of adding a radically polymerizable crosslinking agent and a radical polymerization initiator to the polymer and then heating and / or irradiating with light, and the like.

[0097] In the solution polymerization method, as the method of adding each charged component, any appropriate adding method can be adopted as long as the effects of the present invention are not impaired. Examples of such adding methods include batchwise and continuous methods.

[0098] When using an N-vinyl lactam-based monomer as the monomer component in the solution polymerization method, it is preferable to include a step of adding an organic acid to the obtained polymer after the polymerization reaction. By adding an organic acid to the obtained polymer, the amount of the residual N-vinyl lactam-based monomer in the polymer can be reduced. As such an organic acid, any appropriate organic acid can be adopted as long as the effects of the present invention are not impaired. Examples of such organic acids include organic compounds having acid groups such as a carboxyl group, a sulfonic acid group, a phosphonic acid group, a sulfuric acid group, and a phosphoric acid group. Examples of such organic acids include malonic acid, oxalic acid, succinic acid, aspartic acid, citric acid, glutamic acid, fumaric acid, malic acid, maleic acid, phthalic acid, trimellitic acid, pyromellitic acid, propionic acid, heptanoic acid, octanoic acid, glycolic acid, salicylic acid, lactic acid, L-ascorbic acid, benzoic acid, methanesulfonic acid, benzenesulfonic acid, laurylbenzenesulfonic acid, p-toluenesulfonic acid, benzenephosphonic acid, lauryl sulfate, and the like. The organic acid may be only one kind or two or more kinds.

[0099] As the amount of the organic acid used, any appropriate amount can be adopted as long as the effects of the present invention are not impaired. Such an amount is, for example, preferably 0.01% by mass to 5% by mass, more preferably 0.05% by mass to 3% by mass, and still more preferably 0.1% by mass to 1% by mass based on 100% by mass of the N-vinyl lactam-based monomer charged in the reaction step. If the amount of the organic acid used is within the above range, while reducing the amount of the residual N-vinyl lactam-based monomer in the obtained polymer, the amount of the organic acid (salt) can also be reduced. Note that the organic acid (salt) represents an organic acid and / or a salt of the organic acid, and the salt of the organic acid is mainly a neutralized product of a base added in the neutralization step described later and the organic acid.

[0100] As the reaction time between the organic acid and the polymer, any appropriate reaction time can be adopted as long as the effects of the present invention are not impaired. Such a reaction time is preferably 10 minutes to 3 hours, and more preferably 30 minutes to 2 hours. When the polymer is a crosslinked polymer, it takes more time for the organic acid to penetrate into the inside of the polymer than in the case of a non-crosslinked polymer. However, if the reaction time between the organic acid and the polymer is 10 minutes or more, the organic acid can sufficiently penetrate into the polymer, and the amount of the residual N-vinyl lactam-based monomer in the obtained polymer can be more sufficiently reduced. Also, from the viewpoint of productivity, the reaction time between the organic acid and the polymer is preferably 3 hours or less.

[0101] In the solution polymerization method, it is preferable to include a step of aging the polymer (aging step) after the polymerization reaction. As the temperature in the aging step, any appropriate temperature can be adopted as long as the effects of the present invention are not impaired. Such a temperature is preferably 70°C to 150°C, and more preferably 80°C to 100°C. If the aging temperature is within the above range, the polymerization of the residual N-vinyl lactam-based monomer can be promoted.

[0102] In the solution polymerization method, the aging time in the aging step can be any appropriate aging time as long as the effects of the present invention are not impaired. Such an aging time is preferably 10 minutes to 5 hours, and more preferably 30 minutes to 3 hours.

[0103] In the solution polymerization method, when including the step of adding an organic acid, the aging step is preferably carried out before the step of adding the organic acid.

[0104] In the solution polymerization method, the aging step is preferably carried out while crushing the polymer. In the solution polymerization method, when including the step of adding an organic acid, by crushing, since the organic acid can sufficiently penetrate into the polymer, the amount of residual N-vinyl lactam-based monomer in the obtained polymer can be more sufficiently reduced. The crushing of the polymer can be carried out by a commonly used method, for example, a method of crushing using a kneader and the like.

[0105] In the solution polymerization method, when adding an organic acid, it is preferable to include a neutralization step after the step of adding the organic acid. As a method of neutralization, it is preferable to add a base after reacting the organic acid with the polymer. Examples of such a base include ammonia; aliphatic amines such as monoethanolamine, diethanolamine, and triethanolamine; aromatic amines such as aniline; hydroxides of alkali metals such as sodium hydroxide and potassium hydroxide. Among these bases, preferably, ammonia, aliphatic amines, and hydroxides of alkali metals, more preferably, ammonia, monoethanolamine, diethanolamine, sodium hydroxide, and potassium hydroxide. Such a base may be only one kind or two or more kinds.

[0106] In the solution polymerization method, other steps may be included. Examples of other steps include a drying step, a pulverization step, a classification step, a granulation step, and the like.

[0107] In the drying step, drying refers to an operation for increasing the solid content, and generally, it is sufficient that the solid content is increased compared to that before drying, and the solid content is increased to preferably 95% by mass or more, more preferably 96% by mass or more. The upper limit of the solid content is ideally 100% by mass, and in reality, it is preferably 99% by mass. Drying and polymerization may be performed simultaneously, or drying during polymerization and drying after polymerization may be used in combination. In the solution polymerization method, which preferably involves a drying step of drying using a drying device after polymerization, if an organic acid addition step is included, it is preferable to perform the drying step after the organic acid addition step. The solid content of the polymer refers to a value measured by the method described in the Examples.

[0108] The temperature of the drying step is preferably 80°C to 250°C for 50% or more of the total time of the drying step, and more preferably 80°C to 250°C for substantially 100% of the total time of the drying step. The drying temperature range is preferably 80°C to 250°C, more preferably 110°C to 220°C, and even more preferably 120°C to 200°C. The drying may be performed at a constant temperature or may be performed by changing the temperature. By setting the temperature of the drying step in this way, the various physical properties of the polymer can be further improved. The drying temperature may be determined by the heat medium temperature, and if it cannot be determined by the heat medium temperature, it may be determined by the material temperature.

[0109] Examples of the drying method in the drying step include hot air drying, windless drying, reduced pressure drying, infrared drying, and microwave drying. Among these, it is more preferable to use hot air drying. When using hot air drying, the drying air volume is preferably 0.01 m / sec to 10 m / sec, and more preferably 0.1 m / sec to 5 m / sec.

[0110] In the pulverization step, it is preferable to use a pulverizer. In the solution polymerization method, when a drying step is included, the pulverization step may be performed before, during, or after the drying step. The pulverization step is preferably performed after the drying step.

[0171] [Production Example 1]: Production of N-vinyl lactam polymer A 2000 ml flask equipped with a stirring device (paddle blade type), a thermometer, a reflux condenser, and a nitrogen inlet tube was initially charged with 900 g of heptane and heated in an oil bath at 100 °C under a nitrogen atmosphere. After the temperature in the flask became constant, the dropping components 1 (N-vinylpyrrolidone: 250 g, acrylic acid: 0.25 g, pentaerythritol triallyl ether: 0.5 g) and the dropping component 2 (t-amyl peroxy-2-ethylhexanoate (manufactured by Arkema Kishu Co., Ltd., Lupersol 575): 2.0 g, heptane: 50 g) were started to be added. The dropping component 1 was metered and added at a constant rate over 4 hours, and the dropping component 2 was metered and added at a constant rate over 5 hours. Polymer precipitation started about 30 minutes after the start of dropping and the precipitation amount gradually increased. After the addition of the dropping component 2 was completed, heating was continued for an additional 1.0 hour, and then the flask was cooled to terminate the reaction. The temperature in the flask was between 94 °C and 100 °C and tended to increase generally with the passage of time (the median value was 97 °C). Subsequently, the reaction solution was filtered to recover the precipitate which was the polymer, and dried under reduced pressure at 100 °C for 4 hours to obtain a crosslinked product. Since the crosslinked product was obtained as spherical objects of appropriate size, decantation and filtration were completed in a short time, and the influence of air flow and static electricity was small when handling the powder, and it was easy to handle. When observed with a microscope, most were spherical with a diameter of about 200 μm to 600 μm, and the average particle diameter of the spherical objects was 420 μm. When the total amount of the obtained spherical objects was pulverized by a laboratory pulverizer OML-1 manufactured by Osaka Chemical Co., Ltd., it was easily pulverized in about 20 seconds, and an N-vinyl lactam-based polymer was obtained as a fine and uniform crosslinked product in powder form. The solid content of the obtained N-vinyl lactam-based polymer was 99%. The average particle diameter of the obtained N-vinyl lactam-based polymer when dried at 100 °C for 1 hour under a reduced pressure of 0.01 MPa was 17 μm, and the average particle diameter of the swollen body when swollen with deionized water was 2 μm. The reason why the average particle diameter of the swollen body was smaller than that of the powder was considered to be that the powder absorbed water and swelled, and at the same time, the aggregation was loosened and approached the primary particles.
