Abstract:
The invention relates to a process for the preparation of a masterbatch of diene elastomer and reinforcing inorganic filler in accordance with the invention comprises the following successive stages: bringing into contact and mixing one or more aqueous dispersions (B) of one or more hydrophobized reinforcing inorganic fillers, which coagulate(s) spontaneously with the said latex, and one or more diene elastomer latexes (A) in order to obtain a coagulum, without requiring a coagulating agent, recovery of the coagulum, then drying the recovered coagulum in order to obtain the masterbatch.
