ABSTRACT:
The present invention relates to novel methods of stabilizing polymers of acrylonitrile. The polymers are stabilized by the inclusion of small amounts of stable free radicals compounds which act to inhibit the homopolymerization of the acrylonitrile while promoting the reaction of the acrylonitrile with nucleophilic species such as amines and alcohols.
