Patent ID: 8629213

Claim:
A composition comprising: (i) at least one elastomer which is selected from the group consisting of natural rubber and a synthetic polymer or copolymer resulting from the polymerization of a majority of monomers with a molecular weight of less than 400 g/mol; and (ii) at least one supramolecular polymer obtainable by reacting at least one at least trifunctional compound (A) bearing first and second functions, with: at least one compound (B) bearing, firstly, at least one reactive group capable of reacting with the first functions of (A) and, secondly, at least one associative group; and at least one at least bifunctional compound (C) of which the functions are capable of reacting with the second functions of compound (A) in order to form one or more bridges selected from the group consisting of ester, thioester and amide bridges.
