Abstract

PURPOSE: In the production of a polyalkylene oxide containing olefinic groups on the chain terminals, the reaction mixture is made acidic to coagulate the alkali metal compound dispersing in the mixture in the form of colloidal particles, thus facilitating the separation of the purified product.
