摘要： Polyvinyl halide or polyvinyl graft copolymers intimately mixed with a polyester derived mainly from an halogenated bicycloheptene carboxylic acid or anhydride such as chlorendic acid or anhydride and an alkylene glycol or alkylene oxide such as ethylene oxide are provided. The graft copolymers of the invention are obtained by polymerizing a vinyl halide in bulk in contact with an olefin polymer. The graft copolymer compositions of the invention have good clarity and provide improved processing characteristics and increased impact strength without reduction in heat distortion resulting from the addition of the polyester. The improved impact strength polyvinyl halide compositions of the invention can include blends of the polyester of the invention with modifying compounds, such as alkyl methacrylate-butadiene/styrene graft polymer impact modifiers and halogenated polyvinyl chloride. Blends of vinyl halide polymers with the polyesters of the invention provide compositions having improved processability. A reduction in melt viscosity and fusion temperature can be obtained in the blends while maintaining or increasing heat distortion temperature. The compositions of the invention are useful in the production of molds made by extrusion, injection, blow, and sheet molding processes.

摘要： Polyvinyl chloride and polyvinyl chloride containing up to 20 percent of a comonomer can be obtained in the form of small particle size spherical glassy surface particles by a process of bulk polymerization of monomer or monomers comprising two stage polymerization wherein high shear agitation is used during the first stage and low shear agitation is used in the second stage. To obtain a reduction in particle size, the polymerization in the first stage is conducted in contact with at least one of (A) an additive comprising an organic or inorganic, inert, fine particle size material solid at least at reaction temperatures, and insoluble in said monomer or monomers used, and (B) a cationic, anionic, or non-ionic surface active agent. A portion of the polymerization in a second stage reaction is conducted at temperature and pressure sufficient to render the surface of the individual particles or agglomerates glassy and fused. The resulting polymers and copolymers produced have superior plastisol viscosity stability and fusion characteristics and excellent powder flow properties as compared to those of the prior art.
