ABSTRACT:
Methods are provided for making a solution masterbatch containing a diene elastomer in an organic solvent and a reinforcing silica filler dispersed therein, comprising the steps of (a) mixing a precipitated silica having an average particle size substantially equivalent to an average particle size of a powdered silica, with a diene elastomer in a first organic solvent; and (b) desolventizing the mixture to form a solution masterbatch preparation. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics with improved dispersion of fillers, including polymeric nanoparticles. The compounds also demonstrate improved properties, including reduced hysteresis.
