1. A self-healing elastomer system comprising:
- an elastomer having a surface and a core, the elastomer having an elastomer matrix, wherein the elastomer matrix has first functional groups covalently bonded in the interior, anda liquid phase that borders on the surface of the elastomer, the liquid phase containing an additive, wherein the first functional groups and the additive are chosen so that, in the case of damage to the elastomer, the first functional groups that come into contact with the liquid phase enter into a reaction.

Abstract
A self-healing elastomer system is provided. The system includes an elastomer that has a surface and a core. The elastomer has an elastomer matrix. The elastomer matrix has first functional groups covalently bonded in the interior. A liquid phase borders on the surface of the elastomer. The liquid phase contains an additive. The first functional groups and the additive are chosen so that, in the case of damage to the elastomer, the first functional groups that come into contact with the liquid phase enter into a reaction. The invention also concerns methods for producing and using the self-healing elastomer system and suitable elastomers.

17. An elastomer comprising:
-
a surface and a core, an elastomer matrix having first functional groups covalently bonded in the interior with substantially no covalently bonded first functional groups on the surface, wherein; (a) the elastomer matrix has second functional groups which are components of the elastomer matrix or are attached to it, and/or (b) coagents that are not covalently bonded and that have second functional groups, catalysts, reaction initiators, reaction accelerators and/or cross-linking agents are contained in the elastomer matrix, wherein the second functional groups, catalysts, reaction initiators, reaction accelerators and/or cross-linking agents are chosen so that they enter into or catalyze or initiate a reaction with the first functional groups if an additional component penetrates into the elastomer. - View Dependent Claims (18, 19, 20, 21)

22. A method for producing a self-healing elastomer system comprising the steps of:
-
providing an elastomer that has a surface and a core, the elastomer having an elastomer matrix, the elastomer matrix having covalently bonded first functional groups in its interior, and adding a liquid phase that borders on the surface of the elastomer, wherein the liquid phase contains an additive, the first functional groups and the additive being chosen so that, in the case of damage of the elastomer, first functional groups that come into contact with the liquid phase enter into a reaction.
