Abstract
The invention relates to novel Thermoplastic Olefin compositions comprising polypropylene, and ethylene-alpha olefin elastomer and a compatabilizer comprising an ethylene-propylene copolymer having a propylene content of greater than 80 weight percent. The ethylene-propylene copolymer compatabilizer imparts a greater degree of compatibility between the polypropylene and elastomer phases yielding improved physical properties.
