METHOD FOR PRODUCING VINYL ALCOHOL RESIN

摘要

A method of producing a vinyl alcohol resin having a water content of not higher than 10 wt% by performing a multistage dewatering process by means of a kneading machine. The method permits efficient dewatering of a highly hydrous vinyl alcohol resin to ensure easy production of a lower water content vinyl alcohol resin having a water content of not higher than 10 wt%, thereby reducing production costs. Therefore, the method is industrially useful.
