ABSTRACT:
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 C.sub.3 -C.sub.6 -alkenecarboxylic acid to a temperature of from 60.degree. to 100.degree. 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.degree. to 260.degree. C.; and wherein said copolymer comprises from 94 to 99.5 mol % of ethylene and from 0.5 to 6.0 mol % of C.sub.3 -C.sub.6 -alkenecarboxylic acid.
