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.

Abstract: The present disclosure relates to comb-block copolymers and methods thereof. In some embodiments, a copolymer includes a first block comprising an ethylene-propylene copolymer; and a second block comprising a high density polyethylene. In some embodiments, a polyethylene composition includes the copolymer and a branched vinyl/vinylidene-terminated high density polyethylene. In some embodiments, a process for producing a polyethylene composition includes polymerizing ethylene, at a temperature of at least 100° C., by introducing the ethylene to a first catalyst system having a first catalyst compound and a first activator to form a branched vinyl/vinylidene-terminated high density polyethylene. The process includes introducing the branched vinyl/vinylidene-terminated high density polyethylene to additional ethylene, propylene, and a second catalyst system having a second catalyst compound and a second activator. The process includes obtaining the polyethylene composition.
