Abstract
A ternary suspension copolymerization of vinyl acetate, styrene, and divinyl benzene was carried out, and changes in the yield of the insoluble copolymer and weight per cent of vinyl acetate unit in the copolymer obtained were investigated with changing reaction time and composition of the monomer mixture. This copolymer of white granules ranging from 0.45—0.55 mm in diameter was sulfonated with sulfur trioxide gas, saponified with sodium hydroxide in methanol and then washed with hydrochloric acid to obtain a free-acid-type catalyst. The hydrolysis of dextrin in the presence of the catalyst was investigated. The catalytic activity was found to increase with increasing amounts of hydroxyl group in the copolymer, and rate enhancements of up to nine fold were found relative to the reaction in the presence of the catalyst containing no hydroxyl group.
