Process for the preparation of polymers polymethacrylimide.

POLYMERS polymethacrylimide THAT ARE POOR IN GROUPS AMIDA ON THE carboxylic acid are obtained by heating POLYMERS OF 1 TO 60 mol% of methacrylamide and / ON alkyl- and 40 to 99 mol% of alkyl methacrylates O / Y FENILMETACRILATOS IN ALIPHATIC monoalcohol from 170 to 450 (degrees) C.
