  • POLYOLEFIN COMPOSITIONS AND PRODUCTS
    Publication number: 20230357550
    Abstract: A composition comprising a blend of a propylene-based copolymer composition and a polybutene elastomer and having a balance of softness and strength in combination with enhanced optical properties is provided. A film comprising a propylene-based copolymer composition and a polybutene elastomer is also provided. The film can have the propylene-based copolymer composition and the polybutene elastomer as separate layers in a multilayer structure or a single layer can be formed from a blend of the propylene-based copolymer composition and the polybutene elastomer. Methods for making the compositions and films are also provided.

  • Compatibilization of post consumer resins
    Patent number: 11753534
    Abstract: 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.

  • POLYOLEFIN COMPOSITIONS WITH HIGH DIMENSIONAL STABILITY FOR SHEET APPLICATIONS
    Publication number: 20220380584
    Abstract: A polyolefin composition useful for making sheet membranes, as well as other articles of manufacture are described. The composition polyolefin combines a reactor made thermoplastic (rTPO) with at least one linear low-density polyethylene (LLDPE) to improve the mold shrinkage and thermal expansion force compared to a rTPO-only composition, without affecting other properties.
