CA 2274372

The instant invention provides a process for substantially reducing the polymer cement viscosity or reducing the molecular weight distribution of the a conjugated dime polymer synthesized by using a charge of catalytically effective amounts of a rare earth catalyst and an organo magnesium component by adding an organo zinc component to the charge in an amount and under conditions sufficient to reduce the polymer cement viscosity. The invention also contemplates a catalyst compostion for substantially reducing the polymer cement viscosity of a polymer product as well the resultant polymer product.
