ABSTRACT OF THE DISCLOSURE An elastomeric composition comprising a crystalline ethylene/propylene copolymer containing about 65-78% by weight ethylene units and, optionally, units of a mono- reactive 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 1.0-1.4, about 5-30% by weight based on the weight of the total composition of glass fibers randomly dispersed throughout the composition, and about 40- 150 parts, preferably 50-100 parts by weight per 100 parts of said crystalline copolymer or carbon black. The comp- osition has high flexural strength and can be used in automotive trim application.
