  • Master mixture composition including a peroxide
    Patent number: 10138349
    Abstract: Provided is a transparent thermoplastic composition including 70 to 95% by weight of a copolymer of ethylene and of an ethylenic monomer carrying a polar functional group and 5 to 30% by weight of a peroxide, where the copolymer includes from 20 to 45% by weight of the ethylenic monomer carrying a polar functional group. The composition may be used for crosslinking polymers.
    Type: Grant

    Date of Patent: November 27, 2018
    Assignee: Arkema France
    Inventors: Anne-Yvonne Laignel, Catherine Corfias-Zuccalli, Laurent Keromnes
  • MASTER MIXTURE COMPOSITION INCLUDING A PEROXIDE
    Publication number: 20160046786
    Abstract: invention relates to a transparent master mixture that includes an ethylene copolymer ethylene monomer having a polar function (a) and a peroxide (b), characterized in that said composition includes, by weight, from 5 to 30% of (b); from 70 to 95% of (a); and in that the copolymer (a) includes from 20 to 45 wt % of ethylene monomer having a polar function. The invention also relates to a method for producing a master mixture composition including an organic peroxide. The method makes it possible to produce a composition useful for cross-linking of polymers.
