摘要： Methods are provided for making solution masterbatches containing a diene elastomer in an organic solvent and a silica filler, having a first average particle size, that is ground in an organic solvent to form a silica having a reduced second average particle size. Grinding of the silica in the organic solvent, with or without other ingredients including the elastomer, produces a solution masterbatch in which the silica is mixed with and well dispersed in the elastomer. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics allowing for the reduced use of processing aids such as oil. The compound also demonstrates improved properties, including reduced hysteresis.
