    摘要: The present invention aims to provide a production method that can produce an aqueous dispersion containing polyvinylidene fluoride with high productivity. The present invention relates to a method of producing an aqueous dispersion of polyvinylidene fluoride, including: emulsion polymerization of vinylidene fluoride in the presence of a surfactant, an organic peroxide, and water to produce an aqueous dispersion that contains polyvinylidene fluoride. The surfactant has a surface tension of 55 mN/m or smaller when added in an amount of 1000 ppm.

    摘要: An oil-resistant agent containing a modified natural product which is a bio-based compound having at least one carboxyl group and in which a hydroxyl group of a carboxyl group is substituted with an R group, or a carboxyl group is substituted with an Ra group.



    R group: —X—R1 or —X-D-X′—R1.
    Ra group:








    wherein X is a direct bond, —O—, —NR11—, or —S—, and R1 is a hydrocarbon group having 1-40 carbon atoms, or a polysiloxane, D is an alkylene group having 1-10 carbon atoms, X′ is —C(═O)—O—, —O—(═O)—, —C(═O)—NR12—, or —NR12—C(═O)— (where, R11 and R12 are each hydrogen or an alkyl group having 1-40 carbon atoms). Also disclosed is a textile product, an oil-resistant paper, a food packaging material or a food container each including the oil-resistant agent, as well as a method of treating paper with the oil-resistant agent.

    摘要: An organic fine particle comprising a core polymer and a shell polymer. The core polymer has a Tg or a melting point of 15° C. or more, the core polymer has a water contact angle of 100° or more, all monofunctional monomers constituting the core polymer are a hydrophobic core monomer of which homopolymer has a water contact angle of 100° or more, the shell polymer has a Tg or a melting point lower than Tg or the melting point of the core polymer, the shell polymer has a water contact angle of less than 100°, and all monofunctional monomers constituting the shell polymer are a water-insoluble shell monomer of which homopolymer is water-insoluble. Also disclosed is a surface coating structure including the organic fine particle and a water-repellant composition including a dispersion of the organic fine particle.
