Electrical devices including elastÈmeros of ethylene, vinyl alfaolefina, norborneno and polìmeros of ethylene and alpha olefin

摘要

Invention patent: b "electrical devices including elastu00c8meros ethylene, alpha olefin, vinyl norborneno and polu00ecmeros of ethylene and alpha olefin" d .The elastomeric polymers comprising ethylene, alpha - olefin and vinyl norborneno are shown as having the characteristics of extrusion improved electrical properties improved.Healing characteristics improved compared with the elastomeric polymers of ethylene, alpha olefin, diene non conjugadoo containing dienes' - conjugadoos different vinyl norborneno.The elastomeric polymers containing vinyl norborneno generally have an index of branching below 0.5.These elastomeric polymers are combined with up to 30 parts of copolymers of ethylene and alpha olefin catalisados by metaloceno, for improving the physical properties.
