Abstract
PURPOSE: To improve the polymerization stability of a vinyl monomer and to suppress adhesion of the polymer onto the reactor wall, by adding a spcific phosphoric acid ester nonionic surface-active agent together with a poorly water-soluble phosphoric acid metal salt suspension stabilizer to the polymerization system.
CONSTITUTION: A vinyl monomer (mixture) is compounded with a suspension stabilizer composed of a poorly water-soluble phosphoir acid metal salt and 0.0001 - 0.5 wt.% of phosphoric acid ester nonionic surface-active agent expressed by the formula (R is 3-80C alkyl or aralkyl; A is H, Na or K; n is 5 - 50; m is 1 - 3) [e.g. Gafac (trade-mark of Toho kagakuCo., Ltd) GB520, etc.].
