Abstract
A thermoplastic composition comprising 30 to 90 weight percent of a block copolymer formed from a conjugated diene and a monovinylarene, 5 to 35 weight percent of an ethylene-propylene-nonconjugated diene terpolymer, and 5 to 30 weight percent of a thermoplastic polyolefin. The blend exhibits good distortion resistance, solvent resistance, high temperature retention of hardness, and ozone resistance.
