Abstract

PURPOSE: To prepare a seed latex for the preparation of seed-polymerized PVC free from undesirably fine particles, by the emulsion polymeriation of vinyl cholride adding an anionic emulsifier first, and thereafter adding a nonionic emulisifier.
CONSTITUTION: A seed latex for the seed polymerization is prepared by emulsion polymerization of vinyl chloride or a vinyl monomer mixture consisting mainly of vinyl chloride, in an aqueous medium. An anionic emulsifier (0.01W0.6 wt.% on the basis of the monomer) is added to the system during the polymerization, and thereafter a nonionic emulsifier (≥0.2 wt.% on the basis of the monomer) is added to the system prior to the completion of the polymerization. As the addition of the nonionic emulsifier suppresses the formation of micells during the seed polymerization, the generation of the additional polymer seeds during the polymerization is retarded
