Publication number: 20230050126Abstract: Methods for processing polyolefin recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. polyolefin recyclate feedstocks can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed polyolefin recyclates. Processed polyolefin recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both polyolefin recyclate and/or pre-consumer polyolefins.Type: ApplicationFiled: June 21, 2022Publication date: February 16, 2023Applicant: EQUISTAR CHEMICALS, LPInventors: HARILAOS MAVRIDIS, MICK C.

Publication number: 20140377577Abstract: Disclosed herein are blended polymer compositions having a polyethylene first resin and a mLLDPE resin. The polyethylene first resin have a density of at least 0.926 g/cm3; and the mLLDPE resin has a density of between about 0.910 to about 0.925 g/cm3 and a melt index ranging from about 0.05 to about 5. The amount of the mLLDPE is less than about 20 weight percent based on the weight of the polyethylene first resin and mLLDPE resin; and the mLLDPE resin has a narrower molecular weight distribution than the polyethylene first resin.Type: ApplicationFiled: October 24, 2013Publication date: December 25, 2014Applicant: Equistar Chemicals, LPInventors: Chun D.

Patent number: 8206825Abstract: A coated or jacketed wire or cable, and components thereof are disclosed. The coating, jacket, and components, which comprise a polyolefin and a phenolic polymeric antioxidant, exhibit outstanding oxidative thermal stability (as indicated by the increase in the oxidative inductive time (OIT)), when compared to polyolefins containing traditional non-polymeric antioxidants. A greater improvement in the thermal oxidative stability is observed after the polyolefin mixtures have been aged in water-blocking filler(s).Type: GrantFiled: January 3, 2008Date of Patent: June 26, 2012Assignee: Equistar Chemicals, LPInventors: Marvin R. Appel, Mick C. Hundley, Jeffrey S. Borke, Steven W. Horwatt
