摘要:
The invention relates to a process for the production of stabilized, crosslinkable copolymers of acrylonitrile with N-methylol alkyl ethers of unsaturated carboxylic acid amides and optionally other comonomers by polymerizing in the presence of a stabilizer compound containing a carboxylic acid amide group such as amide, urea or lactam.
