Abstract

A process and articles for continuously making a tetrapolymer can use two reactors connected in series with two saturated hydrocarbon streams, two injections of ethylene monomer, two injections of propylene monomer, and two injections of two different non-conjugated diene monomers simultaneously. Also, the process has a metallocene catalyst and a metallocene co-catalyst in the first reactor and a Ziegler-Natta catalyst, a Ziegler-Natta co-catalyst, and optionally a promoter in the second reactor. This process allows for the creation of products with high molecular weights while utilizing continuous flow reactors in series. The process allows for manufacture of anti-vibration articles made from the high molecular weight tetrapolymers.
