Zinc ionomer rubber activator

摘要

Curable rubber compositions and cured articles are based on the use of zinc activator compositions for the sulfur cure. Activator compositions contain zinc and a polymeric component having a plurality of COOH groups, at least some of which are neutralized with the zinc. With polymeric zinc activators, sulfur cure can be activated at levels of zinc below those used in conventional systems.
