ABSTRACT The present invention is an improved method for stabilizing acetal copolymers by hydrolyzing the copolymer product in a low energy reaction process wherein undesirable side products are continuously and efficiently removed by melting and extruding the unhydrolyzed oxy- methylene copolymer into a hydrolysis reaction zone in which the necessary reactants are intimately contacted with the copolymer, preferably by means of flow division and rearrangement mixing technique. Subsequently, the hydrolyzed copolymer product is devolatilized to remove the unwanted side products by passing it through a devola- tilization zone preferably having more than one devolatilization port and a vacuum source from which negative pressure is available for application to the devolatilization ports so that the undesired products may be effectively removed.
