Beschreibung
Zusammenfassung:	An elastomeric composition comprising a crystalline ethylene/propylene copolymer containing about 65-78% by weight ethylene units and, optionally, units of a monoreactive nonconjugated diene sufficient to provide up to 1 gram mole of carbon-carbon double bonds per kilogram of copolymer, said copolymer having an inherent viscosity of about 0.8-1.6, preferably about 1.0-1.4, about 40-150, preferably 50-100, parts by weight carbon black per 100 parts of the total copolymer composition, and about 5-30% by weight based on the weight of the total composition of glass fibers randomly dispersed throughout the composition. The composition when molded has a high modulus of elasticity and can be used in automotive trim application.
