摘要：
Copolymers according to the invention contain a new crosslinking system based on carbonamide and/or N-methylol carbonamide groups in the copolymer, the crosslinked polymers containing the following structural units ##STR1## in which R represents a straight-chain or branched aliphatic hydrocarbon radical having 0 to 9 carbon atoms,R represents a hydrogen atom or a methyl radical, andR represents hydrogen or a --CH.sub.2 OH-- group and have molecular weights of between 10.sup.3 and 10.sup.6.The invention also relates to a process of making the copolymers, which have among other advantages a superior resistance to solvents. They are useful as coating compositions and the like.
