Abstract

PURPOSE: To obtain the title flaky copolymer readily soluble in cold water, by gelatinizing dissolving, and drying a starch-polyvinyl acetate graft copolymer mixed with an alkali metal.
CONSTITUTION: 0.5W10 wt% an alkali metal, e.g. sodium hydroxide, is added to a starch-polyvinyl acetate graft copolymer (A), which is gelatinized, dissolved, and dried to give the objective starchpolyvinyl aleohol graft copolymer. The degree of grafting of the copolymer (A) is preferably 0.5W10%.
