Abstract
Thermoplastic compositions are described comprising blends of cross-linked polyalkenamer rubber and crystalline thermoplastic polyolefin resin.
Claims21
A thermoplastic composition comprising a blend of about 15 to about 95 parts by weight thermoplastic crystalline polyolefin resin and about 85 to about 5 parts by weight cross-linked polyalkenamer rubber per 100 total parts by weight polyolefin resin and polyalkenamer rubber, in which the polyalkenamer rubber is cross-linked to the extent that no more than fifty weight percent of the rubber is extractable in boiling xylene.
An elastoplastic composition comprising a blend of about 75 to 25 parts by weight thermoplastic crystalline polyolefin resin and about 25 to 75 parts by weight polyalkenamer rubber per 100 total parts by weight polyolefin resin and polyalkenamer rubber in which the polyalkenamer rubber is cross-linked to the extent that no more than twenty weight percent of the rubber is extractable in boiling xylene, which composition is elastomeric and processable as a thermoplastic.
