METHOD OF GRAFTING ETHYLENICALLY UNSATURATED CARBOXYLIC ACIDDERIVATIVES ONTO THERMOPLASTIC POLYMERS USING HYDROXYLAMINE ESTERS

摘要

The invention relates to a method of grafting unsaturated carboxylic acid derivatives onto thermoplastic polymers, which comprises heating a mixture o f thermoplastic polymer, unsaturated carboxylic acid or carboxylic acid derivative and a hydroxylamine 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-C 6- 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.
