| 摘要 |
The present invention is directed to a peroxide curable rubber compound containing a butyl rubber polymer, an olefin polymer of ethylene, at least one alpha-olefin and optionally at least one diene, and a non-polymeric multi-unsaturated peroxide curable compound. The present invention is also directed to a peroxide curable rubber compound containing a butyl polymer, an EPDM rubber polymer and divinylbenzene or di- or tri-(meth)acrylate. Also the present invention is directed to a process for preparing a peroxide curable rubber compound by mixing a butyl rubber polymer, a polymer of ethylene, at least one alpha-olefin and optionally, at least one diene and non-polymeric multi-unsaturated peroxide curable cure modifier in the presence of a peroxide curing agent.
