Abstract (en)
[origin: WO2014161756A1] The invention concerns a method for preparing a master batch of diene elastomer and reinforcing filler, the reinforcing filler consisting of a filler at least partially coated with silica comprising the following successive steps: - preparing at least one dispersion of reinforcing filler in water, - bringing an elastomer latex into contact with the aqueous dispersion of reinforcing filler and mixing same in the presence of a metal salt comprising an at least divalent metal element, to obtain a coagulum, - recovering the coagulum, - drying the recovered coagulum to obtain the master batch; the molar ratio of metal cations, defined as the number of moles of metal cations of the metal salt per surface unit of reinforcing filler, is between 9.3*10-7 and 1.875 *10-5 mol/m2.
