摘要： The present invention is a polyolefin composition, which comprises a thermoplastic olefin polymer and a polyethylene. The thermoplastic olefin polymer (TPO) comprises a polypropylene and an olefin copolymer and is present in an amount of about 10 weight percent to about 50 weight percent; the TPO has a density in the range of about 0.85 g/cm3 to about 0.92 g/cm3 and a flexural modulus of less than about 700 MPa as measured by ISO 178. The polyethylene is either a medium density polyethylene or a high density polyethylene and present in an amount of about 50 weight percent to about 90 weight percent. The polyolefin composition is useful for preparing articles of manufacture such as sheets, roofing membranes, geomembranes, soft skins, drawn tapes, drawn fibers, and drawn filaments.

摘要： This disclosure provides for compatibilizer compositions that are useful in compounding polypropylenes and ethylene elastomeric copolymers for injection molding applications. The compatibilizer includes a combination of: Component A of polypropylene homopolymers or polypropylene copolymers containing small amounts of ethylene; and Component B of propylene bipolymers with ethylene and/or other α-olefin comonomers, the bipolymer having a relatively high proportion of propylene moieties, for example, 50-75% propylene. Compared to known or conventional compatibilizer formulations, the bipolymer Component B is relatively propylene rich and generally can be used in the injection molding composition in lower concentrations.
