  • Patent number: 11976182
    Abstract: Methods may include modifying the crystallization properties of a polymer composition including a polyolefin and a nucleating agent with the structure: wherein R1 and R2 are independently hydrogen, alkyl, alkenyl, or aryl with the proviso that at least one of R1 or R2 is a carbon chain having 1 to 12 carbons with at least one of the carbons in the carbon chain covalently bound to the polyolefin, and wherein the alkyl, alkenyl, or aryl may be substituted with one or more carboxylate groups; and M is a metal selected from Group I of the Periodic Table.

  • Publication number: 20240052146
    Abstract: Ethylene copolymer compositions having a density of 0.902 g/cm3 or less exhibit rapid crystallization behavior. The ethylene copolymer compositions comprise a first ethylene copolymer, a second ethylene copolymer and optionally a third ethylene copolymer, where the number average molecular weight of the first ethylene copolymer is greater than the number average molecular weight of the second ethylene copolymer. The ethylene copolymer compositions are useful in the formation of monolayer and multilayer films.

  • Publication number: 20230035963
    Abstract: Disclosed herein are processes for producing blends of recycled polymeric material and virgin polyethylene. Post-consumer recycled plastic (PCR) can vary widely with respect to composition which includes mixtures of variable amounts of different polar and non-polar polymers such as polyethylene, polypropylene, ethylene vinyl alcohol, and polyamide. Mixing PCR and virgin polyethylene is inconsistent, partially due to variability, and frequently results in a final product with poor mechanical and optical properties. The process described herein of adding PCR to a solution polymerization process provides another option for blending PCR and virgin polyethylene that offers an ability to exert greater control on the properties of the final product, independent of the composition of the PCR.

  • Patent number: 11046835
    Abstract: Polymeric compositions may include one or more adjunct polymers selected from a group of an ionomer and a polar polymer; and an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition. Polymer compositions may include a nonpolar matrix polymer; one or more adjuncts selected from the group of an ionomer, a polar polymer, a metal salt, or combinations thereof. Polymer compositions may also include an intelligent additive, wherein when exposed to the external stimuli, the intelligent additive triggers a color change in the polymeric composition, wherein after at least 17 hours of exposure to the external stimuli, the polymer composition exhibits a ?E of at least 8 or more, maintaining the ?E of at least 8 or more for at least 5 days after the exposure to external stimulus is ceased.

  • Publication number: 20210190742
    Abstract: Packaging materials may include a packaging material formed from an intelligent polymer composition, wherein the intelligent polymer composition includes a matrix polymer and an indicator, wherein the indicator triggers a color change in the intelligent polymeric composition when exposed to an external stimulus, and wherein the intelligent polymer composition is configured to contact a material enclosed within the packaging material. Methods may include forming a packaging material from an intelligent polymer composition, wherein the intelligent polymer composition includes a matrix polymer and an indicator, wherein the indicator triggers a color change in the intelligent polymeric composition when exposed to an external stimulus, and wherein the intelligent polymer composition is configured to contact a material enclosed within the packaging material.
