Abstract

Impact modified compositions having good impact performance can be made from a thermoplastic (e.g., a polyolefin such as polypropylene or HDPE) and a multi-block ethylene/α-olefin interpolymer. The compositions are easily molded and often have particular utility in making, for example, automotive facia, parts and other household articles.
