  • Patent number: 7572862
    Abstract: The invention relates to a process aid for use in rigid thermoplastic compositions, and especially in rigid polyvinylchloride (PVC) compositions. The process aid is an acrylic terpolymer of methylmethacrylate, butyl acrylate and styrene at an optimal ratio to produce a significant reduction in melt process viscosity. The resulting reduction in extrusion melt torques enables manufacturers of rigid PVC products to have higher throughput production rates.

  • Patent number: 7452596
    Abstract: A polyvinyl chloride-based fiber of the present invention is a fiber formed with a vinyl chloride resin composition that comprises (a) 100 parts by weight of vinyl chloride resin, and (b) 0.2 to 20 parts by weight of crosslinked vinyl chloride resin in which a weight fraction of constituents that are insoluble in tetrahydrofuran is 18 to 45% and a viscosity average degree of polymerization of constituents that are soluble in tetrahydrofuran is 500 to 1800, in which a cross-sectional shape of the fiber comprises a combination of at least two of circles, ellipses, and parabolas. When this fiber is used as artificial hair, it is possible to provide style changeability without impairing matte properties and touch of the vinyl chloride-based fiber. Furthermore, the fiber of the present invention can be produced stably by melt-spinning, and thus an industrial advantage also is provided.

  • Patent number: 7339004
    Abstract: Methods are described for preparing graft copolymers from poly(vinyl chloride) or vinyl chloride copolymers comprising reacting these materials with sources of selected metal-centered free radicals in the presence of one or more monomers that can undergo free-radical addition polymerization. The metal-centered free radicals used are capable of abstracting chlorine atoms from the starting polymer to form C-centered radicals that add to the monomer(s) in order to start the growth of branches via a free-radical route. This method is an effective method for producing PVC graft copolymers, and can be used to produce PVC graft copolymers having novel compositions. The methods of the invention are particularly useful for providing highly branched PVC graft copolymers.
