Abstract
Thermoplastic elastomeric compositions, comprising blends of high unsaturation diene rubber and thermoplastic olefin resin in which the rubber is cured, exhibit superior physical properties including improved toughness.
Claims20
An elastomeric thermoplastic composition comprising a blend of about 25-45 parts by weight of crystalline thermoplastic polyolefin resin and about 75-55 parts by weight of vulcanized high unsaturation diene rubber particles of a size below about 50 microns dispersed throughout said resin per 100 total parts by weight of resin and rubber, which rubber is a homopolymer of a diolefin or copolymer in which the major component of the polymer chain is derived from a diolefin.
