Abstract

Methods of making polymers by polymerizing conjugated diolefin in a hydrocarbon solvent in the presence of an initiator are described. Trialkyl or triaryl siloxy iminosilane functionalizing agents are reacted with the polymer, followed by desolvatizing the polymer. The resulting polymer not only has good filler interaction and processability, but results in a polymer with stable Mooney viscosity. A polymer made by the process of the present invention, including silica, and carbon black fillers, and rubber compositions, and tires containing side walls and treads containing the polymers are also described.
