Abstract
The present invention is directed to a catalyst system for synthesizing rubbery polymers, such as polybutadiene rubber, styrene-butadiene rubber, isoprene-butadiene rubber, or styrene-isoprene-butadiene rubber, that are amine functionalized and have a high trans microstructure. The catalyst system, in one embodiment, includes (a) an organolithium amine compound, (b) a group IIa metal salt of an amino glycol or a glycol ether, (c) an organoaluminum compound, and optionally (d) an amine compound. The amine functionalized rubbery polymers can be utilized in tire tread rubbers where the rubbery polymers may provide desirable wear properties without substantially sacrificing other performance characteristic(s), e.g., traction properties.
