  • RUBBER COMPOSITIONS COMPRISING AN EPOXIDE DIENE ELASTOMER AND A CROSS-LINKING SYSTEM
    Publication number: 20240101797
    Abstract: A rubber composition contains: an elastomer matrix comprising at least one diene elastomer comprising epoxide functions, at least one reinforcing filler, and a system for crosslinking said polymer, comprising at least one organopolyphosphorus compound of general formula (I) in which A represents a covalent bond or a hydrocarbon group comprising at least 1 carbon atom, which is optionally substituted and which optionally comprises one or more heteroatoms, and the Rs represent, independently of one another, a hydrocarbon group comprising at least 1 carbon atom or a hydrogen atom.

  • Method for synthesising a polymer bearing at least one phosphonate group, polymer obtained by said method and composition containing same
    Patent number: 10752706
    Abstract: A process for synthesizing a polymer bearing at least one phosphonate group in the polymer chain is provided. The process comprises at least the reaction of a starting polymer bearing at least one nucleophilic function in the polymer chain with at least one electrophilic compound bearing both a phosphonate group and an electrophilic function. The electrophilic function is selected from the halide function, the acyl halide function, the ester function, the carboxylic acid function and the isocyanate function.

  • Method for synthesising a polymer having a hydroxyaryl group, product obtained using said method and composition containing same
    Patent number: 10315463
    Abstract: The invention relates to a process for the synthesis of a polymer bearing one or more pendant hydroxyaryl groups, comprising the reaction of a polymer bearing at least one epoxide functional group with a nucleophilic compound simultaneously bearing the hydroxyaryl group and a nucleophilic functional group selected from the group consisting of the phosphonic acid functional group and its ionic form.
