Abstract (en)

[origin: WO2013053737A1] The invention relates to a method for preparing a masterbatch of natural rubber and silica, comprising the following successive steps of: doping the silica with magnesium, preparing at least one dispersion of the thus-doped silica in water, bringing into contact and mixing a natural rubber 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.
