Abstract

PURPOSE: A dispersion stabilizer for the suspension polymerization of vinyl compounds which contains as the main component a partially saponified polyvinyl alcohol treated with aldehyde and which enalbes suspension polymerization without causing adhesion of scale to polymerization vessel and gives vinyl polymers with steep particle size distribution.
CONSTITUTION: A dispersion stabilizer for the suspension polymerization of vinyl compounds containing as the main component a partially saponified polyvinyl alcohol which was treated with 0.005W3wt% based on partially saponified polyvinyl alcohol on dry base, preferably 0.01W2wt% of an aldehyde including dialdehydes, preferably glyoxal, and which has an average saponification degree of 60W95mol%, and an average polymerization degree of 100W3000, preferably 300W2500.
