Process for the production of water-soluble hydrolyzed products of polyacrylonitrile polymers

摘要

A process for the production of water-soluble hydrolyzed polyacrylonitrile polymers, wherein the acrylonitrile is polymerized in the presence of 1-8% by weight of hydrolyzed polyacrylonitrile and hydrolyzed without intermediate isolation from the reaction mixture.
