In organic chemistry, a vinyl halide is a compound with the formula CH₂=CHX (X = halide). The term vinyl is often used to describe any alkenyl group. For this reason, alkenyl halides with the formula RCH=CHX are sometimes called vinyl halides. From the perspective of applications, the dominant member of this class of compounds is vinyl chloride, which is produced on the scale of millions of tons per year as a precursor to polyvinyl chloride. Polyvinyl fluoride is another commercial product. Related compounds include vinylidene chloride and vinylidene fluoride.
Water repellent composition, method for producing non-fluoropolymer, treatment method, and article
The present invention relates to a water repellent composition comprising a non-fluoropolymer having a structural unit based on a long-chain alkyl (meth) acrylate monomer, a structural unit based on a halogenated ethylene monomer, and a structural unit based on a (meth) acrylate monomer having a polysiloxane structure, the molecular weight of the (meth) acrylic acid ester monomer having a polysiloxane structure is 1000-3600, and the ratio of structural units based on a halogenated ethylene monomer to the total amount of structural units of the non-fluoropolymer is 1-12 mass%.

Water repellent composition, method for producing non-fluoropolymer, treatment method, and article
The present invention relates to a water repellent composition comprising a non-fluoropolymer, the non-fluoropolymer has a structural unit based on a long-chain alkyl (meth) acrylate monomer, a structural unit based on a halogenated ethylene monomer, a structural unit based on a (meth) acrylate monomer having a blocked isocyanate structure, and a structural unit based on a (meth) acrylamide monomer having a specific structure. The proportion of the unit based on the (meth) acrylate monomer having a blocked isocyanate structure is 0.5-10% by mass and the proportion of the structural unit based on the (meth) acrylamide monomer is 0.5-10% by mass with respect to the total amount of the structural units of the non-fluoropolymer.

Polyacrylonitrile-based fiber for artificial hair, method for manufacturing said fiber, and head decoration product containing said fiber
PCT designated stageWO2026110542A1WigsMonocomponent synthetic polymer artificial filamentPolymer scienceAcrylonitrile
The present invention relates to a polyacrylonitrile-based fiber for artificial hair, the polyacrylonitrile-based fiber containing an acrylonitrile copolymer, wherein the acrylonitrile copolymer contains a constituent unit derived from acrylonitrile and a constituent unit derived from a vinyl halide, the average circularity of a transverse cross section of the polyacrylonitrile-based fiber for artificial hair is 0.80 or greater, and the calculated average inclination angle RΔa of a line roughness curve element in a direction orthogonal to the length direction of the fiber is 13.0 to 30.0 degrees on the surface of the polyacrylonitrile-based fiber for artificial hair. As a result of this configuration, provided is a polyacrylonitrile-based fiber for artificial hair, said fiber having favorable curl setting properties when using hot water; a method for manufacturing said fiber; and a head decoration product containing said fiber.
