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).gtoreq.110.degree. 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.degree. 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
.alpha.-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.
