PREPARATION OF STYRENE BUTADIENE RUBBER MASTERBATCH USING POLYAMIDE AND AN EPOXIDIZED SILICA

摘要

A functionalized silica for incorporation into natural and synthetic polymers in latex form using precipitated or fumed silica with at least two organosilicon coupling compounds in an aqueous suspension to allow polyamide to load into the polymer latex or to allow polyurethane to load into the polymer latex without disturbing silica-polymer bonds. Polymer-silica reinforced masterbatches are prepared by addition of the functionalized silica slurry using the formed functionalized silica having two different silanes, one for coupling to polyamide or polyurethane and the polymer, the other for connecting directly to the polymer.
