Abstract:
1. A process for continuously making a blend of a terpolymer with a tetrapolymer, comprising an ethylene monomer, a propylene monomer, and at least two non-conjugated diene monomers, the process comprising: a. in a first reactor continuously making tetrapolymers, comprising the ethylene monomer, the propylene monomer, and the at least two non-conjugated diene monomers, comprising: b. in a second reactor continuously making a liquid phase ultrahigh molecular weight ENB EPDM terpolymer comprising ethylene monomer, propylene monomer, and a first non-conjugated diene monomer by: c. continuously blending the resultant tetrapolymer with the liquid phase ultrahigh molecular weight ENB EPDM terpolymer forming a low damping high strength polymer with high density impact absorbency and heat resistance.
