Abstract
The invention disclosed herein relates to methods for vulcanizing elastomeric materials. The method comprises providing a mixture of ZnO and an amphiphilic triblock copolymer selected from the group consisting of rosin and C.sub.18 -C.sub.24 fatty acid esters of polyethylene glycol and the use of the mixture for vulcanizing an elastomeric component with sulfur. The mixture not only improves the dispersion of zinc salts in the elastomeric composition but also reduces mold fouling by reducing the migration of zinc salts to the interfacial area of the elastomeric composition.
