ABSTRACT:
The invention relates to a method of grafting unsaturated carboxylic acid derivatives onto thermoplastic polymers, which comprises heating a mixture of thermoplastic polymer, unsaturated carboxylic acid or carboxylic acid derivative and a hydroxy-lamine ester having at least one structural unit of formula (I) or (I′) wherein X is hydrogen, C1-C36alkyl, C2-C36alkenyl, C2-C18alkynyl, C6-C10aryl, —O—C1-C18alkyl —O—C6-C10aryl, —NH—C1-C18alkyl, —NH—C6-C10aryl, —N(C1-C6alkyl)2; X′ is a direct bond or C1-C36alkylene, C2-C36alkenylene, C2-C36alkynylene, —(C1-C6alkylene)-phenyl-(C1-C6alkylene) or a group in a processing apparatus for thermoplastic polymers, to above the softening point/melting point of the thermoplastic polymer and allowing the components of the mixture to react with one another
