ABSTRACT:
A paintable, reactor grade thermoplastic olefin (TPO) comprising a blend of elastomer and polypropylene. The elastomer is present in an amount of about 10 to 35% by weight, based on the weight of the TPO. The elastomer comprising about 40 to about 60% by weight polyethylene, based on the weight of the elastomer. The TPO has a viscosity ratio of polypropylene to elastomer of about 50:1 to about 700:1.
