Abstract:
1. A continuous polymerization process for preparing a random ethylene interpolymer, the process comprising: (A) polymerizing ethylene, and an α-olefin comonomer selected from the group consisting of propylene and 1-butene and mixtures thereof under continuous random polymerization conditions in the presence of single site catalyst system employing an ionic activator having cyclic ligands shielding a central charge bearing atom, at a temperature of from 140° C. to 250° C. at a conversion of ethylene of from 80 to 99% and a comonomer conversion of at least 20% and (B) devolatilizing the polymer to provide an ethylene copolymer having a density of from 0.85 to 0.92 g/cm
