Publication number: 20230357550Abstract: 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.Type: ApplicationFiled: May 2, 2023Publication date: November 9, 2023Applicant: EQUISTAR CHEMICALS, LPInventors: BRYAN S. SCHLEY, FABIO CECCARANI, RYAN KRAMB

Patent number: 11753534Abstract: 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.Type: GrantFiled: November 16, 2021Date of Patent: September 12, 2023Assignee: Equistar Chemicals, LPInventors: Nicholas M. Briggs, Ryan Kramb, Bryan S. Schley, Timothy J. Skillman, Jeffrey J. Strebel, Jeanine A. Smith, David C. Holliman, Rocio S. Garay, Gilles Jobin

Publication number: 20220380584Abstract: 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.Type: ApplicationFiled: May 20, 2022Publication date: December 1, 2022Applicant: LYONDELLBASELL ADVANCED POLYMERS INC.Inventors: RYAN KRAMB, BRYAN S. SCHLEY, FABIO CECCARANI

Patent number: 11124618Abstract: Foamed reactor made thermoplastic polyolefins (rTPOs), and articles made therefrom, are described. The compositions have an rTPO combined with a foaming agent. The foaming agent can be a physical blowing agent and/or a chemical foaming agent, and may include optional nucleating agents. Some compositions utilize a masterbatch having one or more chemical foaming agents to foam the rTPOs. The rTPOs have a large melt flow rate range and flexural modulus range that translate into a broad scope of potential applications and foamed architecture. This allows the combination of rTPOs and foaming agents to be fine-tuned for selected foaming application.Type: GrantFiled: June 14, 2019Date of Patent: September 21, 2021Assignee: LyondellBasell Advanced Polymers Inc.Inventors: Vassilios Galiatsatos, Fabio Ceccarani, Chichang Shu, Ryan Kramb, Ignazio Triassi

Patent number: 10723049Abstract: 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 ?-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.Type: GrantFiled: July 13, 2017Date of Patent: July 28, 2020Assignee: Equistar Chemicals, LPInventors: Ryan Kramb, Jeanine A.

Publication number: 20190382549Abstract: Foamed propylene-based reactor made polyolefins, and articles made therefrom, are described. The compositions have a resin that is a reactor made propylene based random copolymer or terpolymer with high comonomer content, combined with a foaming agent. The foaming agent can be at least one physical blowing agent or at least one chemical foaming agent, and may include optional nucleating agents. Reactor made copolymers and terpolymers have a large range of high comonomer content and therefore have physical properties such as increased flexibility, high gloss, lower sealing temperature, and improved compatibility with other polyolefins. These properties translate into a broad scope of potential applications and foamed architecture. This allows the combination of the copolymer or terpolymer, and foaming agents to be fine-tuned for selected foaming application.Type: ApplicationFiled: June 14, 2019Publication date: December 19, 2019Applicant: A.
