Abstract

The polymer compounds according to the invention, comprising special amidines, mercapto compounds and elastomers, are mainly suitable for the production of thermally stable, halogen-containing vulcanized rubbers. The vulcanized, halogen-containing rubbers obtained by means of the polymer compounds are distinguished by a reduced tendency to undergo unwanted subsequent vulcanization and are stable towards thermal and oxidative degradation at high storage temperatures.
