Abstract

Compositions having good low temperature impact performance made from a thermoplastic (e.g., a polyolefin such as polypropylene) and either at least one linear ethylene/C.sub.5 -C.sub.20 .alpha.-olefin or at least one substantially linear ethylene/C.sub.3 -C.sub.20 .alpha.-olefin polymer are disclosed. The compositions are easily molded and have particular utility in making automotive facia, parts and other household articles.
