Coagulated Styrene- Vinylpyridine-Butadiene Ter-polymer latex as Secondary Accelerator in Sulfonamide-Sulfur Curing System

摘要

In the present study,coagulated styrene- vinylpyridine-butadiene ter-polymer latex (VP latex) is used as a secondary accelerator to increase the cure rate in the sulfonamide-sulfur curing system in natural as well as synthetic rubber-based compounds.The activation energy is observed to be lower when coagulated VP latex is used as a secondary accelerator.All other physical properties are observed to be comparable.It is found that a small amount of coagulated VP ter-polymer is sufficient to increase the reaction rate.However,it is also found that coagulated VP latex alone is not a satisfactory accelerator.
