Abstract
A process and articles for continuously making a tetrapolymer using 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 with two metallocene catalysts and two metallocene co-catalysts. This process allows for the creation of products with high molecular weights while utilizing continuous flow reactors in series, preventing an additional blending step. The process allows for manufacture of anti-vibration articles made by the tetrapolymers.
