Abstract
A thermoplastic polyolefin composition which is capable of being shaped and repeatedly recycled, comprises propylene-based polymers, said composition being modified with 0.01-5 wt % of organic oligomeric silanes selected from partially hydrolyzed alkoxy substituted vinyl, allyl or methacryl silanes, and blends thereof, and 0.0005-0.5 wt % of a compound capable of generating free radicals.
