Abstract
A process and articles for continuously making a tetrapolymer using two reactors connected in series with two unsaturated hydrocarbon streams, two injections of ethylene monomer, two injections of propylene monomer, and two injections of two different non-conjugated diene monomers with a Ziegler-Natta, a catalyst, a co-catalyst, and an optional promoter. The process allows for the creation of products and articles with high molecular weights while utilizing continuous flow reactors in series. The process allows for manufacture of anti-vibration articles made by tetrapolymers.
