Preparation of copolymers of ethylene with alkenecarboxylic acids

摘要

A process for the preparation of copolymers of ethylene and dicarboxylic acid in the presence of a free-radical inhibitor. The process comprises of warming a mixture of ethylene and C3-C6-alkenecarboxylic acid to a temperature of from 60 DEG to 100 DEG C. before addition of the free-radical inhibitor. The maximum polymerization temperature to recover said copolymers of ethylene is in the range of from 100 DEG to 260 DEG C.; and wherein said copolymer comprises from 94 to 99.5 mol % of ethylene and from 0.5 to 6.0 mol % of C3-C6-alkenecarboxylic acid.
