Abstract:
The present invention is related to a propylene-based injection molded composition made from a polymer blend comprising from 45 to 85 wt % of a polymer blend modifier having a weight average molecular weight of 10,000 to 100,000 g/mole and from 15 to 55 wt % of a propylene-based elastomer having a weight average molecular weight of from 100,000 to 300,000 g/mole, where the weight percent of the polymer blend modifier and the propylene-based elastomer are based on the total weight of the polymer blend. The polymer blend modifier comprises a first propylene-based polymer and a second propylene-based polymer, where the first and second propylene-based polymers are different and are individually selected from a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin.
