Claim Text:
1. A polymerization process comprising: (A) polymerizing ethylene and optionally one or more α-olefins in the presence of a catalyst to form a semi-crystalline ethylene-based polymer in at least one reactor; the catalyst comprising an organometallic catalyst thereby forming an ethylene-based polymer composition in the at least one reactor, wherein the catalyst is a metal complex of a polyvalent aryloxyether corresponding to the formula: where M Ar T R R R D is independently in each occurrence halo or a hydrocarbyl or trihydrocarbylsilyl group of up to 20 atoms not counting hydrogen, or 2 R D groups together are a hydrocarbylene, hydrocarbadiyl, diene, or poly(hydrocarbyl)silylene group; wherein step (A) is conducted in the presence of from 5 to 20 mmol/m wherein step (A) is conducted in the presence of the following conditions: (i) from greater than 0:1 to 65:1 molar ratio of triethylaluminum to the catalyst; and (ii) from 0.1:greater than 0 to 5:1 molar ratio of triethylaluminum to modified methylalumoxane.
