Abstract: The present invention relates to a thermoplastic composition, a thermoplastic composite, and a method for producing the thermoplastic composite. In the method for producing the thermoplastic composite, a polymer, an acid-modified lignin with a specific element content and a compatibilizer with a specific melt flow index and a specific maleic anhydride content are used to produce the thermoplastic composite. Hydroxy groups of the acid-modified lignin react with maleic anhydride groups of the compatibilizer to generate ester bonds via an in-situ reaction catalyzed by acidic groups of the acid-modified lignin to enhance compatibility between the polymer and the lignin, thereby increasing a mechanical strength of the resulted thermoplastic composite.

Abstract: This invention offers a functional vinyl halide polymer that has excellent processing properties for the end-user processing without any extra processing aid. This functional vinyl halide polymer has good fusion, lubrication and melting strength in processing. The finished products show a good characterization of high transparence, low air-mark and low flow-mark. The functional vinyl halide polymer is produced by a solution, bulk or suspension polymerization. Vinyl halide or a monomer mixture comprising mainly vinyl halide is polymerized in an aqueous medium in the presence of an acrylic copolymer latex/powder to obtain the functional vinyl halide polymer. The functional vinyl halide polymer manufacturing process mainly comprises the copolymerization or graft-polymerization of: (A) 90.0 wt %˜99.9 wt % based on the total composition of the vinyl halide or the monomer mixture, and (B) 10.0 wt %˜0.

Abstract: This invention relates to a method for graft-copolymerizing vinyl chloride monomer to a polyfluorine resin to produce resins of improved physical properties and processability parameters. The vinyl chloride monomer and polyfluorine resin are first treated in a highly alkaline medium and at a high temperature, and the mixture is stirred. Suspension agent(s), water and an initiator are added to the mixture after the temperature thereof has been lowered. The resultant mixture which has been stirred and homogenized is heated to a temperature at which polymerization is completed. Thereafter the mixture is neutralized, washed, and dried. A product having improved impact strength and resistance to heat and abrasion results.

Abstract: The present invention relates to a polymerization process for polymerizing olefinically unsaturated monomer or monomers, wherein inorganic salts are employed to substitute for the traditional emulsifiers employed in the polymerization recipe. The polymerization of olefinically unsaturated monomer or monomers is conducted in the presence of a water soluble initiator. An electrolytic solution of inorganic salt and a buffer solution are introduced into the polymerization mixture at a particular time during reaction period to adequately adjust pH value of the reaction mixture. Further, it is essential to alter the speed of agitation during polymerization by a two-stage operation.
