Abstract

PURPOSE: To provide suspension stabilizer for suspension polymn, which produces a vinyl polymer having an appropriate apparent specific gravity, good plasticizer absorption and sharp particle size distribution, consisting of a partially saponified PVA having anionic hydrophilic gp. on its side chain.
CONSTITUTION: A copolymer of an unsaturated aliph. carboxylic acid or an ester thereof and vinyl acetate is saponified to obtain a suspension stabilizer consisting of partially saponified PVA contg. anionic hydrophilic gp. of 0.02W5mol% on its side chain and having a degree of saponification of 60W80mol%. The anionic hydrophilic gp. of the suspension stabilizer imoparts an anionic property to polymer particles. The distribution of the particles is promoted by electrical repulsion. When primary particles are agglomerated and adhere to one another to grow, appropriate voids are formed and a porous vinyl polymer is obtained.
