ABSTRACT:
The invention relates to a process for the production of a stabilized crosslinkable copolymer of acrylonitrile which comprises copolymerizing at least 65% by weight of acrylonitrile with from 0.1 to 3% by weight of an N-methylol acyl ester of an ethylenically unsaturated carboxylic acid amide, optionally from 0.5 to 5% by weight of an N-methylol alkyl ether of an ethylenically unsaturated carboxylic acid amide and, optionally, at least one other copolymerizable comonomer in an aqueous medium in the presence of a redox catalyst and in the presence of at least one water-soluble compound containing a carboxylic acid amide group.
