Abstract
Described herein is a thermoplastic physical blend composition comprising (a) from 20 to 95 wt. % based on the total polymer content of a first polymer component that includes polypropylene having a melting point (Tm)≧110° C.; and (b) from 80 to 5 wt. % based on the total polymer content of a second polymer component that includes a reactor blend obtainable from a solution process, the reactor blend including: (i) from 2 to 98 wt. % based on the total weight of the SPC of a propylene polymer having 60 wt. % or more units derived from propylene, including isotactically arranged propylene derived sequences and Tm<105° C. or a Heat of Fusion<45 J/g, or both; and (ii) from 98 to 2 wt. % based on the total weight of the SPC of an ethylene α-olefin elastomer having either no crystallinity or crystallinity derived from ethylene, wherein (c) the FPC and the SPC are physically blended together to form the composition.
