  • Compatibilized silica in nitrile rubber and blends of nitrile rubber and styrene butadiene rubber compositions
    Patent number: 8329794
    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.
    Type: Grant

  • PROCESS FOR MAKING COMPATIBILIZED SILICA AND NITRILE POLYMER COMPOSITIONS
    Publication number: 20110166262
    Abstract: A process for forming a compatibilized silica and nitrile polymer blend in latex form is described herein. The process can include treating a silica with a coupling agent in aqueous suspension to form a compatibilized silica slurry. The coupling agent can have the capacity of chemically reacting with the surface of the silica to bond the coupling agent thereto. The process can include blending at least a portion of the compatibilized silica slurry into a styrene butadiene polymer latex, forming a silica styrene butadiene polymer latex, and blending at least a portion of the compatibilized silica slurry into an acrylonitrile butadiene polymer latex, forming a silica acrylonitrile butadiene polymer latex. The process can include blending the silica styrene butadiene polymer latex with the silica acrylonitrile butadiene polymer latex, forming the compatibilized silica and nitrile polymer blend.
