ABSTRACT:
A compatibilized silica for incorporation into natural and synthetic polymers in latex form or dry blending operations is described. Said compatibilized silica is formed by the reaction of precipitated or fumed silica with organosilicon coupling compounds in aqueous suspension. Polymer-silica reinforced masterbatches are prepared by addition of the compatibilized silica slurry to natural and synthetic polymer latices. Also described is a process for preparing the compatibilized silica.
