摘要： The present disclosure provides a process. In an embodiment, the process includes contacting, under polymerization conditions, one or more C6-C14 α-olefin monomers with a bis-biphenylphenoxy catalyst. The process includes forming a polymer composed of one or more C6-C14 α-olefin monomers, and having an absolute weight average molecular weight (Mw(abs)) greater than 1,300,000 g/mol and a Mw(abs)/Mn(abs) from 1.3 to 3.0.

摘要： The present disclosure provides a process and resultant composition. In an embodiment, the process includes providing an ethylene/propylene/non-conjugated polyene terpolymer (EPDM) having at least 3.5 wt % non-conjugated polyene. The process includes reacting the EPDM with a metal-Lewis acid, and forming a rheology-modified EPDM. The rheology-modified EPDM has (i) a z average molecular weight (Mz) from greater than 500,000 g/mole to 10,000,000 g/mole, (ii) a Mz/Mw from 3 to 10, (iii) a g value from 0.4 to 1.0, (iv) a z value from 1.0 to 3.5, (v) a Mooney viscosity from 50 to 150, and (vi) a tan delta value from 0.1 to less than 1.0.
