ABSTRACT:
The polymer compounds according to the invention prepared from specific amidines, zinc mercapto compounds and elastomers are ideally suitable for the production of thermally stable rubber vulcanisates containing halogen. The vulcanisates of rubbers containing halogen obtained by means of the polymer compounds are distinguished by a reduced tendency towards unwanted post-vulcanization and, at elevated storage temperatures, are resistant to thermal and oxidative degradation.
