1. A method for attenuating vibrations and/or shocks, said method comprising:
providing a damper assembly, said damper assembly comprising at least one moving part and at least one supramolecular polymer in contact with said at least one moving part, said supramolecular polymer being obtained by reacting:
a) 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;
b) 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, and
exposing said at least one moving part to said vibrations and/or shocks, so as to attenuate the same.
