  • COPOLYMER OF ETHYLENE AND A 1,3-DIENE
    Publication number: 20230028231
    Abstract: A copolymer of ethylene and a 1,3-diene, containing more than 50 mol % of ethylene units and containing 1,2-cyclohexanediyl units is provided. The 1,3-diene is 1,3-butadiene or a mixture of 1,3-dienes containing 1,3-butadiene, and the copolymer consists of a main chain and one or more side chains.

  • Continuous method for producing a diene elastomer
    Patent number: 11427653
    Abstract: A continuous method for producing a diene elastomer is provided. The method comprises a polymerization reaction of a catalytic system with at least one conjugated diene monomer to be polymerized in solution in a solvent. The catalytic system is based on at least a rare earth organic salt and an alkylating agent, in at least two full polymerization reactors in series. A portion of the conjugated diene monomer to be polymerized is introduced into a polymerization reactor subsequent to the first polymerization reactor.
    Type: Grant
    Filed: December 4, 2018
    Date of Patent: August 30, 2022

  • Functional ethylene and 1,3-butadiene copolymer
    Patent number: 11155656
    Abstract: An ethylene/1,3-butadiene copolymer containing ethylene units, butadiene units and UD units of cyclic, 1,2-cyclohexanediyl structure, and bearing, at one of its chain ends, an alkoxysilyl or silanol function, functional group F1 is provided.

  • Functional copolymer consisting of a 1,3-diene and an olefine
    Patent number: 11104755
    Abstract: A copolymer of a 1,3-diene and of an olefin selected from the group consisting of ?-monoolefins, ethylene and mixtures thereof is provided. The copolymer bears, at one of its chain ends, an alkoxysilyl or silanol function, functional group F1, and the copolymer is different from a copolymer of a 1,3-diene and a vinylaromatic monomer.
