Abstract
Injection moldable thermoplastic polyolefin resins containing from about 20 to about 40 wt % EPR dispersed in a continuous highly isotactic polypropylene having good paintability. Reactor prepared resins, or RTPO resins, containing highly isotactic polypropylene and from 20 to 30 wt % of an EPR component comprising from about 40 to about 55 wt % ethylene are particularly attractive for use in the production of automotive trim and fascia.
