Abstract
A method of hydrolyzing a polymer of a monomer substance of which acrylonitrile or methacrylonitrile constitutes at least 50% by weight of the total monomer content, which comprises suspending finely divided polymer in a mixture of 5 to 50% by weight of water and 50 to 95% by weight of an alcohol with the following structure: ** figure ** where m and n are integers from 1 to 4, inclusive and x is an integer from 0 to 3, inclusive, in the presence of a metal hydroxide alkaline, heating the suspension to a temperature above 40º c.
