[0166] [Polymerization method] The method for producing the stripping agent composition disclosed herein is: (1) Polymerize an acrylic acid ester monomer (a1) having a hydrocarbon group with 7 to 40 carbon atoms and a monomer (a2) having an amide group, or (2) The process involves polymerizing an acrylic acid ester monomer (a3) ​​having an amide group and a hydrocarbon group having 7 to 40 carbon atoms to obtain an amide group-containing polymer.

[0167] Amide group-containing polymers can be produced by known polymerization methods, and the conditions for the polymerization reaction can be arbitrarily selected. Examples of such polymerization methods include solution polymerization, suspension polymerization, emulsion polymerization, and condensation polymerization.

[0168] In solution polymerization, monomers are dissolved in an organic solvent in the presence of a polymerization initiator, followed by nitrogen purging and heating and stirring at a temperature of 30 to 120°C for 1 to 10 hours. Examples of polymerization initiators include azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, and diisopropyl peroxydicarbonate. The polymerization initiator is used in an amount of 0.01 to 20 parts by weight, for example, 0.01 to 10 parts by weight, per 100 parts by weight of monomer.

[0169] Organic solvents are inert to monomers and dissolve them, and may include esters (e.g., esters with 2 to 40 carbon atoms, specifically ethyl acetate and butyl acetate), ketones (e.g., ketones with 2 to 40 carbon atoms, specifically methyl ethyl ketone, diisobutyl ketone, and methyl isobutyl ketone), and alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically ethanol, butanol, and isopropyl alcohol). Specific examples of organic solvents include acetone, chloroform, HCHC225, isopropyl alcohol, cyclohexane, benzene, toluene, xylene, petroleum ether, tetrahydrofuran, 1,4-dioxane, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, ethyl acetate, butyl acetate, 1,1,2,2-tetrachloroethane, 1,1,1-trichloroethane, trichloroethylene, perchloroethylene, tetrachlorodifluoroethane, and trichlorotrifluoroethane. The organic solvent is used in an amount of 10 to 3000 parts by weight, for example, 50 to 2000 parts by weight, per 100 parts by weight of the total monomers.

[0170] Water-soluble organic solvents may be used as organic solvents. For example, water-soluble organic solvents such as ketones (e.g., acetone, methyl ethyl ketone, etc.) or alcohols (e.g., propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, ethanol, etc.) may be used.

[0171] In emulsion polymerization, a method is employed in which monomers are emulsified in water in the presence of a polymerization initiator and an emulsifier, and then polymerized by stirring at a temperature of 50 to 80°C for 1 to 20 hours after nitrogen purging. Polymerization initiators include water-soluble ones such as benzoyl peroxide, lauroyl peroxide, t-butyl perbenzoate, 1-hydroxycyclohexyl hydroperoxide, 3-carboxypropionyl peroxide, acetyl peroxide, azobisisobutylamidine dihydrochloride, sodium peroxide, potassium persulfate, and ammonium persulfate, as well as oil-soluble ones such as azobisisobutyronitrile, benzoyl peroxide, di-t-butyl peroxide, lauryl peroxide, cumene hydroperoxide, t-butyl peroxypivalate, and diisopropyl peroxydicarbonate. The polymerization initiator is used in an amount of 0.01 to 20 parts by weight, for example, 0.01 to 10 parts by weight, per 100 parts by weight of monomer.

[0172] To obtain a polymer aqueous dispersion with excellent stability during storage, it is desirable to polymerize the monomers by micronizing them in water using an emulsifying device that can impart strong crushing energy, such as a high-pressure homogenizer or an ultrasonic homogenizer. Various emulsifiers, including anionic, cationic, and nonionic types, can be used as emulsifiers, typically in an amount ranging from 0.5 to 20 parts by weight per 100 parts by weight of monomer. It is preferable to use anionic and / or nonionic and / or cationic emulsifiers. If the monomers are not completely miscible, it is preferable to add a compatibilizer that allows them to be sufficiently miscible, such as a water-soluble organic solvent or a low molecular weight monomer. Adding a compatibilizer can improve emulsifying and copolymerizing properties.

[0173] As the water-soluble organic solvent, the organic solvents mentioned above may be used. For example, acetone, methyl ethyl ketone, ethyl acetate, propylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol, tripropylene glycol, ethanol, etc., may be used in a range of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of water. In addition, as low molecular weight monomers, methyl methacrylate, glycidyl methacrylate, 2,2,2-trifluoroethyl methacrylate, etc., may be used in a range of 1 to 50 parts by weight, for example, 10 to 40 parts by weight, per 100 parts by weight of the total amount of monomers.

[0174] In polymerization, a chain transfer agent may be used. The molecular weight of the polymer can be changed depending on the amount of chain transfer agent used. Examples of chain transfer agents include mercaptan group-containing compounds such as lauryl mercaptan, thioglycol, and thioglycerol (especially alkyl mercaptans (e.g., with 1 to 40 carbon atoms)), and inorganic salts such as sodium hypophosphite and sodium bisulfite. The amount of chain transfer agent used may be in the range of 0.01 to 10 parts by weight, for example, 0.1 to 5 parts by weight, per 100 parts by weight of the total amount of monomer.

[0175] Copolymerization can be carried out by a single charge (single-stage polymerization) or by divided charges (multi-stage polymerization, especially two-stage polymerization).

[0176] [Liquid media] The stripping agent composition may contain a liquid medium. The liquid medium is water, an organic solvent, or a mixture of water and an organic solvent. Preferably, it is a mixture of water and an organic solvent.

[0177] Examples of organic solvents include esters (e.g., esters with 2 to 40 carbon atoms, specifically ethyl acetate and butyl acetate), ketones (e.g., ketones with 2 to 40 carbon atoms, specifically methyl ethyl ketone and diisobutyl ketone), alcohols (e.g., alcohols with 1 to 40 carbon atoms, specifically isopropyl alcohol), aromatic solvents (e.g., toluene and xylene), and petroleum solvents (e.g., alkanes with 5 to 10 carbon atoms, specifically naphtha and kerosene). The organic solvent is preferably a water-soluble organic solvent. The water-soluble organic solvent may contain compounds having at least one hydroxyl group (e.g., polyhydric alcohols such as alcohols and glycol-based solvents, or ether forms of polyhydric alcohols (e.g., monoether forms)).

Hydrogen silicone (e.g., methyl hydrogen silicone) is a type of polydiorganosiloxane in which part of the side chain is replaced with hydrogen, and the hydrogen atoms are directly bonded to silicon atoms. When using hydrogen silicone, a catalyst may be used to improve reactivity. For example, zinc, tin, manganese, cobalt, iron, and amine-based catalysts can be used. Organic acid metal salts are preferred as catalysts, and fatty acids are preferred as organic acids. From a safety standpoint, zinc stearate can be used. It is preferable to use the catalyst at a concentration of 10 to 40% relative to the methyl hydrogen silicone, as this makes it easier to exhibit its effect. Two or more types of amino-modified, epoxy-modified, carboxy-modified, and methyl hydrogen silicones may be mixed. All of them are silicones having reactive groups and preferably have film-forming properties. Film-forming properties refer to the ability of a silicone to form a solid film, rather than an oily or gel-like film, after being applied to the fiber surface in an emulsion state.

Specific examples of alpha-olefins include 1-tricosene, 1-tetracosene, 1-hexacosene, 1-octacosene, 1-triaconthene, and 1-dotriaconthene. The hydrosilylation reaction may be carried out by reacting the α-olefin with the SiH group-containing silicone in a stepwise or one-time manner, if necessary, in the presence of a catalyst.

[0198] The amounts of SiH-containing silicone and α-olefin used in the hydrosilylation reaction can be appropriately selected depending on the SiH group equivalent or number-average molecular weight of the SiH-containing silicone.

[0326] The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples.

[0327] <Testing Method> The examination procedure is as follows:

[0328] [Peelability] The resulting aqueous dispersion was adjusted to 5%, and glassine paper was 25.8 g / m². 2 The coating was applied using a wire bar. After drying with a drum dryer, the coating amount was checked and found to be 5.0 g / m². 2 The following was done: Glassine paper coated with a release agent composition was attached to a piece of resin plate, and the adhesive side of polyester adhesive tape No. 31B (Nitto Denko Corporation) was attached to the coated surface in a strip shape measuring 25 mm x 180 mm. This was then sandwiched between glass plates, with a pressure of 70 g / cm². 2 The tape was aged at room temperature for 24 hours under the specified load. After aging, in accordance with JIS Z0237, the end of the polyester adhesive tape No. 31B was measured using an Autograph tensile tester (Shimadzu Corporation) at a peeling angle of 180° and a peeling speed of 0.3 m / min. After measuring the peeling force, adhesive tape No. 31B was again applied to the same surface under the same conditions, and the peeling force was measured again to determine the peeling force when used repeatedly. The results for the examples and comparative examples are shown in Table 1.

[0329] [Adhesion to substrate] After peeling, we checked whether any of the broken base material, such as glassine paper or the release agent, was adhering to the adhesive surface of the adhesive tape. ○: No substrate or release agent is attached at all. △: The base material or release agent is attached only to the edges of the adhesive tape. ×: The entire surface of the adhesive tape is covered with the base material or release agent. The results of the examples and comparative examples are shown in Table 1.

[0330] [Example 1] A 500 ml reactor equipped with a stirrer, thermometer, reflux condenser, dropping funnel, nitrogen inlet, and heating device was prepared, and 100 parts of the solvent methyl ethyl ketone (MEK) were added. Subsequently, under stirring, monomers consisting of 78 parts of stearyl amide ethyl acrylate (C18AmEA, melting point: 70°C), 16 parts of hydroxybutyl acrylate (HBA, Tg: -40°C), and 6 parts of dimethylaminoethyl methacrylate (DM) (total monomers: 100 parts), and 1.2 parts of the initiator perbutyl PV (PV) were added in this order. This mixture was mixed and stirred under a nitrogen atmosphere at 65-80°C for 12 hours to carry out copolymerization. The solid content concentration of the obtained copolymer-containing solution was 50% by weight. The molecular weight of the obtained copolymer was analyzed by gel permeation chromatography, and the mass-average molecular weight in polystyrene terms was 230,000. As a post-treatment, 142 g of a 0.4% aqueous acetic acid solution was added to 50 g of the obtained copolymer solution and dispersed. Then, the solution was heated using an evaporator, and MEK was removed by distillation under reduced pressure to obtain a milky white copolymer aqueous dispersion (volatile organic solvent content of 1% by weight or less). Deionized water was added to obtain an aqueous dispersion with a solid content of 15% by weight. The melting point of this copolymer was 66°C.

[0331] [Example 2] In a 500ml plastic container, 30g of a water-soluble glycol solvent was added as an organic solvent, 120g of pure water was added as a liquid medium, 48g of stearyl acrylate and 5g of diacetone acrylamide were added as long-chain aliphatic hydrocarbon group-containing (meth)acrylates, and 2.0g of cationic emulsifier, 2.0g of sorbitan fatty acid ester, 6.0g of polyoxyethylene alkyl ether and 0.1g of acetic acid were added as surfactants. The mixture was heated to 60°C, stirred with a homomixer at 2000 rpm for 1 minute, and then emulsified and dispersed using ultrasound for 15 minutes. Next, this emulsified dispersion was transferred to a 500 ml autoclave, and after nitrogen purging, 0.2 g of lauryl mercaptan and 12 g of vinyl chloride were added as chain transfer agents. Furthermore, 1.0 g of an azo group-containing water-soluble initiator was added, and the mixture was heated to 60°C and reacted for 4 hours to obtain an aqueous dispersion of the polymer. This dispersion was further diluted with pure water to prepare an aqueous dispersion with a non-volatile concentration of 30%.

[0332] [Example 3] An aqueous dispersion was prepared in the same manner as in Example 2, except that 24 g of stearyl acrylate and 24 g of stearyl amide ethyl acrylate were used as the long-chain aliphatic hydrocarbon group-containing (meth)acrylates.

[0333] [Comparative Example 1] IE7045 (Dow Inc.) was used as the aqueous dispersion.
