Abstract

A polymer composition of a compatibilized silica in blends of acrylonitrile butadiene polymer and styrene butadiene polymer comprising six to ninety percent by weight of a compatibilized silica, at least one percent by weight of a coupling agent, at least one percent by weight of a styrene butadiene polymer, and at least one percent by weight of an acrylonitrile butadiene polymer is described herein. The polymer composition can have a minimum amount of at least ten percent by weight of 15:50 ratio, acrylonitrile to butadiene polymer, with the remainder being compatibilized silica.
