Ethylene copolymer and process for the production thereof |
摘要 |
A copolymer of ethylene and an ethylenically alpha , beta -unsaturated acid halogenated phenyl ester represented by the formula (1): <IMAGE> (1) (wherein R is hydrogen or a methyl group, X is a halogen atom, Y is an alkyl group having 4 to 18 carbon atoms, n is 0 or 1, m is an integer of 1 to 5, and l is 0 or an integer of 1 to 4), wherein the halogenated phenyl ester group unit content is about 0.005 to about 10 mol %. This copolymer is excellent in dielectric breakdown characteristics and flexibility, and its excellent performance can be maintained over a long period of time. Thus, it is useful as a superhigh voltage electric wire cable insulative material.
