摘要

The invention relates to an elastomer material including flexible polymer chains containing crosslinking bridges having covalent bonds and crosslinking bridges having noncovalent bonds. The invention also relates to a method for preparing such elastomer material.

主权项

1. An elastomer material comprising flexible polymer chains associated by means comprising a) crosslinking bridges having covalent bonds and b) crosslinking bridges having noncovalent bonds,
the elastomer material having been crosslinked at epoxy functional groups carried by the flexible polymer chains, and the flexible polymer chains having been grafted with 2-aminoethylimidazolidone (UDETA), wherein the molar ratio of UDETA/epoxy is deficient in UDETA.
