    摘要： The present invention pertains to a surfactant free method for manufacturing a fluoropolymer F comprising, preferably consisting of:



    from 45 to 95% by moles of recurring units derived from tetrafluoroethylene (TFE)
    from 5 to 35% by moles of recurring units derived from vinylidene fluoride (VDF)
    from 0.5 to 20% by moles of one or more perfluoroalkylvinylether (PAVE) of formula (I)






    CF2═CF—O—Rf  (I)

    wherein Rf is a C1-C6 perfluoroalkyl group and

    wherein the molar amounts of said recurring units are relative to the total moles of recurring units in said polymer F.

    摘要： The invention relates to a method for attenuating vibrations and/or shocks, said method comprising providing a damper assembly which comprises a moving part and a supramolecular polymer in contact with said moving part, and exposing said moving part to said vibrations and/or shocks, wherein said supramolecular polymer is obtained by reacting: at least one first polymer [polymer (P1)] comprising a polymer chain [chain (R)] consisting of a plurality of non-ionisable recurring units [units (U)], said polymer (P1) having two chain ends (E1, E1′), each end comprising at least one ionisable acid group, and at least one second polymer [polymer (P2)] comprising a polymer chain [chain (R)] consisting of a plurality of recurring units [units (U)], said chain (R) being equal to or different from that of polymer (P1), and said polymer (P2) having two chain ends (E2, E2′), each end comprising at least one ionisable amino group.
