ABSTRACT:
A polyolefin rubber composition consisting essentially of 100 parts by weight of a polyolefin rubber polymer, 10 to 100 parts by weight of a mono-olefin monomer, 1 to 20 parts by weight of a polyolefin polyfunctional monomer, and 0.1 to 15 parts by weight of an organic peroxide, wherein these components are blended and subjected to heat treatment to form a denaturated polyolefin rubber.
The mechanical and electrical characteristics of this denaturated polyolefin rubber do not deteriorate even after long-time subjection to heat treatment, and this material finds application as a rubber for thermally resistant electrical products.
