Abstract: A polymer composition may include a high-density polyethylene (HDPE), in which at least a portion of ethylene from the HDPE is obtained from a renewable source of carbon. The polymer composition may include a primary antioxidant that is an isocyanurate, a secondary antioxidant that comprises a diphosphite, and a neutralizer is a layered double hydroxide. A bicomponent fiber may include the polymer composition. An article may be prepared from the polymer composition or the bicomponent fiber. A product may be prepared from the polymer composition or the bicomponent fiber.

Abstract: A polyethylene composition comprising may include a multimodal high-density polyethylene, comprising at least a lower molecular weight fraction and a higher molecular weight fraction, and a low density polyethylene, wherein the low-density polyethylene is present in an amount of greater than 1 to 20% by percent weight of the total composition. Methods for increasing die swell in blow molding processes may include polymerizing ethylene and optionally one or more alpha-olefin comonomers to obtain a multimodal HDPE comprising at least a lower molecular weight fraction and a higher molecular weight fraction, and blending a low-density polyethylene with the multimodal HDPE.

Abstract: A biobased polymer composition for pharmaceutical articles includes a low density polyethylene, in which at least a portion of ethylene is obtained from a renewable source of carbon. The biobased polymer composition exhibits an Emission Factor ranging from ?3.5 to 0 kg CO2e/kg of the biobased polymer composition, and is biocompatible for use in pharmaceutical packaging. A pharmaceutical article includes the biobased polymer composition and has a volume ranging from 0.04 ml to 10000 ml. A method for forming a pharmaceutical article includes extruding the biobased polymer composition at a temperature ranging from 100 to 250° C. and at a screw speed ranging from 20 to 100 rpm. A method for producing a biobased polymer composition includes polymerizing ethylene at least partially obtained from a renewable source of carbon to form a low density polyethylene.
