[Effects of the Invention]

[0012] According to the present disclosure, there is provided a resin material that contains a polymer compound having a host group and / or a guest group and that exhibits excellent solubility. [Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 shows a photograph of the coating according to Example 5. [Figure 2] FIG. 2 is a graph showing the results of the tensile test on the coating according to Example 5. [Figure 3]FIG. 3 shows a photograph of the coating according to Example 6. [Figure 4] FIG. 4 is a graph showing the results of the tensile test on the coating according to Example 6. DETAILED DESCRIPTION OF THE INVENTION

[0014] <Resin materials> The resin material according to the present disclosure is The composition contains a host body made of a polymer compound having a host group and a guest body made of a polymer compound having a guest group, or a host-guest body made of a polymer compound having a host group and a guest group, and At least one of the polymer compound having a host group and the polymer compound having a guest group, or the polymer compound having a host group and a guest group, contains a siloxane bond.

[0015] The polymer compounds contained in conventional resin materials based on polymer compounds having host groups and / or guest groups often have insufficient solubility in solvents.

[0016] In contrast, the polymer compound contained in the resin material according to the present disclosure has a siloxane bond, which results in relatively improved solubility. Without intending to be limited by theory, it is believed that the resin material according to the present disclosure has a relatively high solubility in non-polar solvents such as hydrocarbon oils and silicone oils due to the polymer compound contained therein having a siloxane bond.

[0017] When the polymer compound constituting the resin material has good solubility, for example, good film-forming properties can be obtained when forming a film using the resin material, which is advantageous. That is, the resin material according to the present disclosure can be dissolved in a non-polar solvent, which improves application properties, and further, since film formation can be performed by volatilizing the non-polar solvent, it is thought that a relatively uniform film can be easily formed.

[0018] Furthermore, the resin material according to the present disclosure contains a polymer compound having a host group and / or a guest group. Such a resin material can form a film by bonding the polymer compounds via host-guest interactions. Because the bond via host-guest interactions is a non-covalent bond, such a film has relatively higher elasticity (smaller Young's modulus) than films formed by bonding polymers via conventional covalent bonds. Therefore, films formed using the resin material of the present application are considered to have excellent elasticity and extensibility.

[0019] Furthermore, polymer compounds having siloxane bonds are relatively chemically stable and are resistant to oxidation and decomposition, and therefore the resin material according to the present disclosure may have superior chemical stability compared to, for example, polymer compounds having only a carbon skeleton.

[0020] The resin material according to the present disclosure can be used, for example, in coating agents, cosmetics, and the like.

[0021] <Host Group and Guest Group> "Host-guest interaction" refers to a bond formed between a host group and a guest group. The host group binds to the guest group by including the guest group. A host-guest interaction occurs when the guest group has a size suitable for being incorporated into the internal space of the host group and the host group and the guest group have an interaction involving at least one of hydrophobic interaction, hydrogen bonding, electrostatic interaction, and coordinate bonding.

[0022] (host group) Examples of the host group include cyclodextrins (CDs). Specifically, α-cyclodextrin, β-cyclodextrin, and γ-cyclodextrin are mentioned. When these groups are used as the host group, stable host-guest interactions can be formed.

[0023] (guest group) The guest group is not particularly limited as long as it is a group that can become a guest group for a corresponding host group. Examples of the guest group include an alkyl group that may have a substituent and an aryl group that may have a substituent. The alkyl group that may have a substituent and the aryl group that may have a substituent as the guest group have 1 to 18, preferably 3 to 12, and more preferably 3 to 9 carbon atoms. Examples of the guest group include a trialkylsilyl group (for example, a trimethylsilyl group, a triethylsilyl group, and a tripropylsilyl group, particularly a trimethylsilyl group).

[0024] Among the guest groups, examples of alkyl groups that may have a substituent include linear, branched, or cyclic C1-18 alkyl groups. Specific examples include alkyl groups such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl, cyclopentyl, hexyl, cyclohexyl, isohexyl, dodecyl, octadecyl, and adamantyl. Of these, an adamantyl group or a butyl group is preferred, and an adamantyl group is particularly preferred. This alkyl group may have one to three substituents, such as a halogen atom (e.g., fluorine, chlorine, bromine, etc.), a carboxyl group, an ester group, an amide group, or an optionally protected hydroxyl group. It may also be an alkyl group to which ferrocene, an organometallic complex, is bonded as a substituent.

[0025] Among the guest groups, the aryl group which may have a substituent includes, for example, a monocyclic or bicyclic or multicyclic aryl group, and specific examples thereof include phenyl, toluyl, xylyl, naphthyl, anthryl, phenanthryl, etc. The aryl group may have 1 to 3 substituents such as an alkyl group (e.g., a C1-18 alkyl group), a halogen atom (e.g., fluorine, chlorine, bromine), a carboxyl group, an ester group, an amide group, an azo group having an aryl group, or an optionally protected hydroxyl group.

[0026] (Combination of host and guest groups) In one embodiment according to the present disclosure, the host group and the guest group in the resin material are any one of the following combinations (a) to (c): (a) the host group is α-cyclodextrin, and the guest group is at least one selected from the group consisting of (1) a linear alkyl group having 4 to 18 carbon atoms, (2) a linear alkyl group having 4 to 18 carbon atoms and a hydroxyl group, (3) a linear alkyl group having 4 to 18 carbon atoms and a carboxyl group, (4) a linear alkyl group having 4 to 18 carbon atoms and an amino group, (5) a cyclic alkyl group, (6) a phenyl group, (7) an azobenzene group, and (8) a cinnamic acid group; (b) the host group is β-cyclodextrin, and the guest group is at least one selected from the group consisting of (1') a t-butyl group, (2') an adamantyl group, (3') an aryl group, (4') an aryl group having a hydroxyl group, (5') an aryl group having a carboxyl group, (6') an aryl group having an amino group, (7') a ferrocenyl group, (8') an azobenzene group, and (9') a dansyl group; (c) the host group is gamma-cyclodextrin, and The guest group is at least one selected from the group consisting of (1") an alkyl group having up to 18 carbon atoms, (2") an alkyl group having up to 18 carbon atoms and a hydroxyl group, (3") an alkyl group having up to 18 carbon atoms and a carboxyl group, (4") an alkyl group having up to 18 carbon atoms and an amino group, (5") an adamantyl group, (6") a group having a cluster composed of carbon atoms, (7") a dansyl group having an aryl group, (8") a ferrocenyl group, and (9") an anthracenyl group.

When both the polymer compound having a host group and the polymer compound having a guest group contained in the resin material according to the present disclosure contain siloxane bonds in their main chains, the heat resistance and weather resistance of the resin material, as well as the solubility in hydrocarbons and silicones, are further improved.

Examples of condensing agents include 1-hydroxybenzotriazole (HOBt; Tokyo Chemical Industry Co., Ltd., H0468, Cas: 80029-43-2) and N,N'-dicyclohexylcarbodiimide (DCC; Nacalai Tesque, Inc., 11913-52, Cas: 538-75-0).

[0113] <Production of Polymer Compound: Siloxane Polymer Compound Having Host Group and Guest Group> The siloxane polymer compound having a host group and a guest group can be obtained, for example, by polymerizing a siloxane polymer compound having a host group produced by the above-mentioned method and a siloxane polymer compound having a guest group produced by the above-mentioned method to form a block copolymer.

[0114] <Production of Polymer Compound: Production of Polymer Compound Having Host Group and / or Guest Group and Siloxane Bond> A polymer compound having a host group and / or a guest group and a siloxane bond can also be produced, for example, by polymerizing a monomer represented by the following formula (5) with a monomer represented by the following formula (6). The manner of the polymerization reaction is not particularly limited, and known methods can be used.

[0117] For each symbol in the above formula (5) and formula (6), the description of each symbol in the above formula (2) and formula (3) can be referred to. E represents a terminal group. E For this, the above description can also be referred to.

[0118] (crosslinking) In one embodiment of the resin material according to the present disclosure, At least one of the polymer compound having a host group and the polymer compound having a guest group, or the polymer compound having a host group and the guest group, is crosslinked. The crosslinking may be by a mechanism other than host-guest interaction, such as by a covalent bond (e.g., siloxane crosslinking).

[0119] For example, a polymeric compound having a host group may be crosslinked to form a host entity, and / or a polymeric compound having a guest group may be crosslinked to form a guest entity.

[0120] Known methods and crosslinking agents for crosslinking polymer compounds may be used depending on the type of polymer compound. Crosslinking may be achieved, for example, by photoirradiation. Examples of crosslinking agents include N,N'-methylenebisacrylamide (MBAAm) and ethylene glycol dimethacrylate (EDMA).

[0121] <Manufacturing of resin materials> The resin material according to the present disclosure can be prepared, for example, by separately producing a polymer compound having a host group and a polymer compound having a guest group, and then mixing the resulting polymer compound having a host group and the polymer compound having a guest group. When mixing the polymer compound having a host group and the polymer compound having a guest group, for example, both may be mixed in a solid state, one or both may be mixed in a liquid state, or one or both may be mixed in a solution state. A method in which one polymer compound is added in a solid state to a solution of the other polymer compound may also be used.

[0122] The conditions for mixing the polymer compound having a host group and the polymer compound having a guest group are not particularly limited, and for example, the mixing temperature, mixing time, mixing means, etc. may be appropriately set.

[0123] In one embodiment of the resin material according to the present disclosure, the resin material is in a paste state at room temperature. A liquid resin material can be obtained by selecting a polymer compound that is in a paste state at room temperature as the polymer compound contained in the resin material. Alternatively, a liquid resin material can be obtained by dissolving the polymer compound in a solvent. A resin material that is in a liquid state at room temperature is particularly preferred because it is relatively easy to form a film from the resin material.

[0124] Examples of polymeric compounds that are liquid at room temperature include polymeric compounds having polyorganosiloxane in the main chain, particularly dimethylpolysiloxane.

[0125] The solvent for dissolving the polymer compound is not particularly limited, but examples include silicone oil and hydrocarbon oil, and the silicone oil is preferably one or more selected from octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, dimethylpolysiloxane, and caprylyl methicone, more preferably one or more selected from decamethylcyclopentasiloxane and dimethylpolysiloxane, and even more preferably dimethylpolysiloxane with a degree of polymerization of 10 or less. Examples of hydrocarbon oil include hydrogenated polyisobutene and isododecane, and isododecane is preferred.

[0126] The polymer compounds contained in the resin material according to the present disclosure may or may not be bonded to each other through host-guest interactions.

[0127] The resin material can be formed into a film. If the resin material is in a film form, it can be used for various purposes in the form of a film, etc. The thickness of the resin material in a film form is not particularly limited and can be set to an appropriate thickness depending on the purpose. For example, the resin material can be adjusted to 1 nm to 1 cm, and in terms of good film-forming properties, it can be adjusted to 1 μm to 100 μm.

[0128] When the resin material is in the form of a film, a covalent bond may be formed between the resin material and a substrate on which the resin material is disposed. Specifically, the film-like resin material may form a covalent bond with a functional group present on the surface of the substrate. In this case, the adhesive strength (adhesion) between the film-like resin material and the substrate can be improved.

[0129] (molding) The method for forming the resin material into a film is not particularly limited, and for example, a wide variety of known film-forming methods can be used. For example, a solution or dispersion of the polymer compound that constitutes the resin material can be prepared, and the film-like resin material can be formed by various film-forming methods, such as coating, casting, or spin coating, using this solution or dispersion. The solvent for preparing the solution or dispersion is not particularly limited, and water, alcohol, or an organic solvent such as toluene can be widely used.

[0130] When the resin material is molded into a film, the film formation method may particularly include the following operations: dissolving a polymer compound having a host group in a solvent to prepare a host solution; preparing a host-guest solution by adding a polymer compound having a guest group to the host solution; and The host-guest solution is applied to an object and dried to form a film.

[0131] Alternatively, in the above method, a guest solution may be prepared by dissolving a polymer compound having a guest group in a solvent, and a host-guest solution may be prepared by adding a polymer compound having a host group to this guest solution.

[0132] Alternatively, the deposition method may in particular comprise the following operations: Mixing a polymer compound having a host group in a paste or liquid state with a polymer compound having a guest group in a paste or liquid state to form a mixture; The mixture is applied to an object to form a film. Either the polymer compound having a host group or the polymer compound having a guest group may be in a paste or liquid form.

[0133] (Additives) The resin material of the present disclosure may contain a polymeric compound having a host group and a polymeric compound having a guest group, or a polymeric compound other than a polymeric compound having a host group and a guest group, as long as the effects of the present invention are not impaired. For example, the polymeric material of the present invention may be physically incorporated into a specific polymeric compound in order to improve the mechanical and chemical properties of the specific polymeric compound. Examples of such specific polymeric compounds include (meth)acrylic resins (acrylic polymers), polyester resins, alkyd resins, polystyrene resins, melamine-formaldehyde resins, polyisocyanate resins, epoxy resins, vinyl chloride resins (e.g., vinyl chloride-vinyl acetate copolymers), ketone resins, and petroleum resins, as well as organic resins such as polyethylene, polypropylene, and chlorinated polyolefins; inorganic resins such as silica gel and silicic acid; fluororesins obtained by polymerizing fluoroolefins, fluororubbers, fluoropaints, fluorine repellents, and fluorine coating agents.

[0210] Then, the solution of polymer compound H7 and polymer compound G1 in isododecane was poured into a 5 cm × 5 cm mold made of Teflon (registered trademark), dried overnight in a windy oven at 130°C, and solidified to obtain a membrane. The obtained membrane was an elastomeric membrane with high elasticity.

[0211] (Evaluation of self-repairing ability) The self-repairing properties of the obtained film were evaluated as follows: (1) Cut the membrane into strips 6 mm wide and 30 mm long. Cut the strip of membrane in the middle to form two pieces. Bringing the two pieces into contact with each other via their cut surfaces; The contacted pieces are sandwiched between overlapping Teflon plates, and the edges of the overlapping Teflon plates are fixed with clips; The mixture was left to stand overnight at 60°C under reduced pressure to obtain a test piece. (2) The test specimen was held at both ends with two grips of a tensile tester, and tensile stress was applied to the specimen along its length. The energy required for the specimen to break (fracture energy kJ / m3) was measured. The specimen broke at the point where the cut surfaces were joined. The ratio of this to the fracture energy measured on a strip-shaped film that had not been cut was calculated to calculate the repair rate for Example 7. The repair rate for Example 7 was 62.1%.

[0212] The evaluation results of the self-repairing property are shown in Table 1. The self-repairing property was evaluated according to the following criteria. 〇: If the repair rate is 50% or more △: When the repair rate is between 1% and 50% ×: The repair rate was less than 1%.

[0213] Example 8 A membrane was produced in the same manner as in Example 7, except that polymer compound H7 and polymer compound G1 were mixed in a molar ratio of 1:1.6, and evaluation was performed in the same manner as in Example 7. The repair rate of Example 8 was 69.1%. The test piece broke at the location where the cut surfaces were joined. The evaluation results are shown in Table 1 below.

[0214] Comparative Example 1 Using the polymer compounds CH-1, which does not have a siloxane bond and has a host group, and CG-1, which has a guest group, as polymer compounds, production of a resin material and film formation were attempted in the same manner as in Example 1. Due to low solubility, film formation was not possible. The evaluation results are shown in Table 1 below.

[0215] Comparative Example 2 Using the polymer compounds CH-2, which does not have a siloxane bond and has a host group, and CG-2, which has a guest group, as polymer compounds, production of a resin material and film formation were attempted in the same manner as in Example 1. Due to low solubility, film formation was not possible. The evaluation results are shown in Table 1 below.

[0216] Comparative Example 3 Using the polymer compounds CH-3, which does not have a siloxane bond and has a host group, and CG-3, which has a guest group, as polymer compounds, production of a resin material and film formation were attempted in the same manner as in Example 1. Due to low solubility, film formation was not possible. The evaluation results are shown in Table 1 below.

[0217] <Reference example 1> Using a side-chain carboxyl-modified silicone oil (polymer compound A1) and the above-mentioned polymer compound G1 as polymer compounds, a resin material was produced and a film was formed in the same manner as in Example 1. In Reference Example 1, although a film could be formed, a solidified film could not be obtained, and therefore the self-repairing property could not be evaluated according to the above-mentioned evaluation method. The evaluation results of solubility, film-forming property, and film elasticity are shown in Table 1 below.

[0218] <Reference example 2> A film was prepared in the same manner as in Example 7 using a side-chain carboxyl-modified silicone oil (polymer compound A1) and a polymer compound H8 having a host group in a molar ratio of approximately 1:1. The evaluation results of the solubility, film-forming ability, film elasticity, and self-repairing ability for Reference Example 2 are shown in Table 1 below. The repair rate of the film according to Reference Example 2 was 0.08%.

[0219] <Reference example 3> When the polymer compound (polymer compound A2) and the polymer compound G1' having a guest group were mixed in a molar ratio of approximately 1:1 to form a film, although a film could be formed, a solidified film could not be obtained, and therefore the self-repairing property could not be evaluated according to the evaluation method described above. The evaluation results of solubility, film-forming property, and film elasticity are shown in Table 1 below.

[0221] Examples 9 and 10 In Examples 9 and 10, experiments were carried out on a resin material having a polymer compound having a host group and no siloxane bond, and a polymer compound having a guest group and a siloxane bond.

[0222] Example 9 A resin material and a film were produced in the same manner as in Example 5, except that 450 mg of polymer compound CH-4 was used as the polymer compound having a host group and 50 mg of silicone resin (siloxane crosslinked product, Silform Flexible Resin (trade name) (manufactured by MOMENTIVE)) was used as the polymer compound having a guest group. The evaluation results are shown in Table 2.

[0223] The film of Example 9 was cloudy. Without intending to be limited by theory, this is thought to be due to the presence of polymer compound CH-4, which does not have a siloxane bond, dispersed in the film. Among the polymer compounds contained in the resin material, polymer compounds having guest groups showed good solubility in solvents.

[0224] Example 10 A resin material and a film were produced in the same manner as in Example 5, except that 450 mg of polymer compound CH-4 was used as the polymer compound having a host group and 50 mg of polymer compound G2 was used as the polymer compound having a guest group. The evaluation results are shown in Table 2.

[0225] The film of Example 10 was cloudy.
