  • Publication number: 20210230325
    Abstract: A copolymer of ethylene and of isoprene, which comprises from 10 to 35 mol % of isoprene units, at least 70% of which are in the 3,4 configuration and a portion of which is in the 1,2 configuration is provided. A copolymer of this type with a reduced crystallinity is synthesized with a much higher productivity than its homologues of ethylene and of butadiene, and also confers improved curing properties on rubber compositions.

  • Publication number: 20210079135
    Abstract: A rubber composition which comprises at least one reinforcing inorganic filler and a highly saturated elastomer comprising 1,3-diene units and ethylene units and bearing, at the chain end, a functional group F1 which is a silanol or alkoxysilane function is provided. The ethylene units represent more than 50 mol % of all the monomer units of the elastomer. The rubber composition has an improved hysteresis/stiffness compromise.

  • Publication number: 20210054118
    Abstract: A copolymer of ethylene and of a 1,3-diene of formula CH2?CR—CH?CH2 is provided. The ethylene units represent between 50 mol % and 95 mol % of the ethylene units and of the units of the 1,3-diene, and the units of the 1,3-diene of 1,2 and 3,4 configuration represent more than 50 mol % of the units of the 1,3-diene. The symbol R represents a hydrocarbon chain having from 3 to 20 carbon atoms. Such a copolymer exhibits an improved compromise between the degree of crystallinity and the stiffness and makes it possible to widen the field of application of ethylene-rich diene copolymers in rubber compositions.

  • Publication number: 20210009729
    Abstract: A copolymer of ethylene and of myrcene, in which the ethylene units represent between 50 mol % and 95 mol % of the ethylene units and of the myrcene units, and the myrcene units of 1,2 and 3,4 configuration represent more than 50 mol % of the myrcene units, is provided. Such a copolymer exhibits an improved compromise between the degree of crystallinity and the stiffness. It therefore makes it possible to widen the field of application of ethylene-rich diene copolymers in rubber compositions, and also to increase the production capacity of a unit for the synthesis of ethylene-rich diene polymers.
