Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a polyvinyl alcohol-polyether-graft copolymer, by which the product is obtained in a form capable of being advantageously used by an injection molding method or a film extrusion method, and by which the graft copolymer containing the vinyl alcohol in a copolymerized form and having a surely adjustable hydrolysis degree can simply be produced without accompanying a complicated process, especially a steam distillation process and a spray drying process. SOLUTION: This method for producing the graft copolymer (P2) having repeating units originated from the vinyl alcohol and having polyether groups comprises reacting a graft copolymer (P1) having repeating units originated from a vinyl alcohol ester and having polyether groups with water and/or at least one 1 to 6C alkanol in the presence of a catalyst in an extruder. Namely, the method for preparing the graft copolymer having repeating units originated from the vinyl alcohol and having the polyether groups comprises reacting the corresponding graft copolymer based on the vinyl alcohol ester with the water and/or at least one 1 to 6C alkanol in the presence of a catalyst in an extruder.
