ABSTRACT:
Modified polyvinyl chloride is produced by suspension polymerization in the presence of monomersoluble catalysts and conventional protective colloids. After polymerization, there is added to the polymerized mixture, 0.1 to 3% by weight, based on the amount of polyvinyl chloride of the latex of a copolymer of 75-95% by weight of methyl methacrylate, 0-20% by weight of styrene, and 5-25% by weight of an acrylic acid ester of 4-8 carbon atoms in the alcohol component. Precipitation of the latex is then effected under continued agitation. Precipitation can be accomplished, for example, thermally or using coagulants. The thus-modified suspension polymer is subsequently obtained by ordinary removal by filtration and drying.
