摘要： Compositions comprising post-consumer recycled (PCR) waste are described. The PCR is combined with at least one virgin resin and a propylene-based compatibilizer that enhances the blend between the PCR and virgin resin as well as improving one or more physical properties of the composition. The propylene-based compatibilizer is a reactor made thermoplastic polyolefin or a heterophasic copolymer with a semi-crystalline matrix and a rubber component. This allows for the selection of a compatibilizer that can shift the composition's physical properties based on the end use application, and provide a stronger, miscible blend.

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 a-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.
