An associative group carrier obtained by thermal irreversible permanent chemical crosslinking, including a crosslinked bridge having a covalent bond, on the other hand, capable of modifying the polymer chain to form a non-covalent bond. In particular, an elastomeric material containing a crosslinked bridge having a thermoreversible non-covalent bond is obtained. An elastomeric material comprising flexible polymer chains that are associated with each other through a permanent cross-linked bridge having a covalent bond and on the other hand via a cross-linked bridge having a non-covalent bond, and having a non-covalent bond A material wherein the bridging bridge comprises an associative group based on a nitrogen-containing heterocycle, wherein the nitrogen-containing heterocycle is selected from imidazolidinyl, triazolyl, triazinyl, bisrailyl and ureidopyrimidyl groups, preferably imidazolidinyl groups.
