METHOD FOR PREPARING A MASTERBATCH OF SYNTHETIC DIENE ELASTOMER AND SILICA

摘要

The invention relates to a method for preparing a masterbatch of synthetic diene elastomer and silica, comprising the following successive steps consisting in: doping the silica with an at least divalent metal element; preparing at least one dispersion of the doped silica in water; contacting and mixing a synthetic diene elastomer latex and the aqueous dispersion of doped silica, in order to obtain a coagulum; recovering the coagulum; and drying the recovered coagulum in order to obtain the masterbatch.
