ABSTRACT:
Chlorinated ethylene-.alpha.-olefin copolymer rubber of the present invention is characterized in that the content of chlorine bonded to primary carbon atom is 0.6% by weight or more and the content of chlorine bonded to tertiary carbon atom is 1.6% by weight or less. This chlorinated ethylene-.alpha.-olefin copolymer rubber has a high vulcanization speed and excels in heat resistance. Additionally, this thermoplastic elastomer composition consisting of this vulcanizate and crystalline polyolefin resin particularly excels in moldability and processibility.
