ABSTRACT:
Polymethacrylimide polymers poor in amide or N-alkylamide groups and in carboxyl and carbonic acid anhydride groups are obtained by heating a copolymer consisting of 1 to 60 mol percent of methacrylamide or/and an N-alkyl-methacrylamide and 40-99 mol percent of an alkyl methacrylate or/and phenyl methacrylate in an aliphatic monoalcohol.
