  • BIO-BASED ELASTOMERIC EVA COMPOSITIONS AND ARTICLES AND METHODS THEREOF
    Publication number: 20220306846
    Abstract: A polymer composition may include an elastomeric ethylene-vinyl acetate, in which at least a portion of ethylene from the elastomeric ethylene-vinyl acetate is obtained from a renewable source of carbon. A curable polymer composition, an expandable polymer composition, articles, cured articles, and expanded articles may include or be formed from such polymer composition. A process for producing a polymer composition may include polymerizing ethylene at least partially obtained from a renewable source of carbon with vinyl acetate to produce an ethylene vinyl acetate copolymer; and mixing the ethylene-vinyl acetate copolymer with an elastomeric polyolefin to produce an elastomeric ethylene-vinyl acetate.
    Type: Application
    Filed: June 13, 2022
    Publication date: September 29, 2022
    Applicant: Braskem S.A.

  • BIO-BASED EVA COMPOSITIONS AND ARTICLES AND METHODS THEREOF
    Publication number: 20220185922
    Abstract: A copolymer may include ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. Embodiments may also be directed to curable polymer compositions, expandable polymer compositions, articles, cured articles, and expanded articles formed from or including such copolymers of ethylene and vinyl acetate, in which the ethylene is at least partially obtained from a renewable source of carbon. A process for producing an ethylene vinyl acetate copolymer may include fermenting a renewable source of carbon to produce ethanol; dehydrating the ethanol, wherein the ethanol is dehydrated to produce ethylene; and polymerizing ethylene and vinyl acetate to produce the ethylene vinyl acetate copolymer.
