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.

Process for continuously making high molecular weight tetrapolymer for use in anti-vibration applications

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.

Process for making high molecular weight tetrapolymer and articles produced therefrom

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.

A low damping high strength polymer with a blend of a terpolymer and a tetrapolymer utilizing ethylene, propylene, and non-conjugated dienes. This polymer allows for the creation of products with high diene contents and broad molecular weight distributions while utilizing a continuous flow reactor and a known catalyst. The polymer allows for these products to be made without gelling or fouling of the reactor, which are problems known in the art.
