Abstract
PURPOSE: Title dispersion stabilizer that contains an ethylene-vinyl ester copolymer or its saponified product, thus giving vinyl chloride polymers having a large particle void that is almost constant among each particle and a sharp distribution of particle size.
CONSTITUTION: Said stabilizer consists of (A) an ethylene-vinyl ester copolymer containing 10W95 mol% of ethylene or its saponified product, preferably a mixture thereof with (B) a polyvinyl alcohol of 60W90 mol% average saponification degree and 100W3000 average molecular weight. When the content of ethylene in component A is lower than 10 mol%, the desirable effect does not develop, and the average saponification degree lower than 60 mol% in component B reduces the properties protecting colloid to broaden the distribution of particle sizes. Further exceeding 90 mol% lowers surface active properties, resulting in lessen void of particles.
