Abstract
PURPOSE: To obtain the titled polymer, consisting of a spherical particle with little void and suitable as a compounding resin, by the presence of a copolymerizable monomer and a chain transfer agent in a system for the polymerization of vinyl chloride, using a gelatineous or cellulosic dispersant.
CONSTITUTION: In the copolymerization of vinyl chloridem, with a monomer m2 copolymerizable with the vinyl chloride in the presence of a gelatinous dispersant (e.g., an acid-treated gelatin; it is preferable to use a polyvinylpyrrolidone together, in view of mechanical properties, etc. of a molded product) or a cellulosic dispersant (e.g., methyl cellulose), and a chain transfer agent (e.g., cyanoacetic acid), a vinyl chloride polymer is prepared by using 0.01W1pts.wt.,100pts.wt., vinyl chloride, of a monomer having larger reactivity r2 with the active terminal group of the monomer m2 as compared with reactivity r1 with the active terminal group of the monomer m1 (e.g., a 1W5C alkyl acrylate), and 0.005W0.15pts.wt. organic compound of chain transfer constant ≥0.02 when vinyl chloride is polymerized at 50°C.
