Abstract
The present invention is directed to a process for forming a high-cis polydiene. The process includes catalyzing a diene polymerization, and terminating the polymerization with an amine-water termination mixture, preferably a TMEDA-water termination mixture. The catalyst system is a mixture of (a) organoaluminum compounds; (b) organonickel compounds; and (c) fluorine-containing compounds.
