The filler is one in which suitable water repellency is imparted to the filler. Hence, by adding this to pulp slurry, followed by a wet papermaking, the filler is efficiently adsorbed onto pulp fibers having anionic property, so that effective sizing performance can be imparted to the paper by using a smaller amount thereof than the internal sizing agent, while reducing the amounts of the internal sizing agent and the aluminum sulfate.

  • 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.
