POLYOLEFIN POLYMERIZATION PROCESS, SEMI-CRYSTALLINE ETHYLENE-BASED POLYMER MADE THEREFROM, AND ARTICLES MADE FROM THE POLYMER |
摘要 |
A polymerization process comprising (A) polymerizing ethylene 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: wherein step (A) is conducted in the presence of from 5 to 20 mmol/m3 triethylaluminum; and wherein step (A) is conducted in the presence of one or both of the following conditions: (i) from greater than 0:1 to 65:1 molar ratio of triethylaluminum to the catalyst; and (ii) from 0.1:0 to 5:1 molar ratio of triethylaluminum to modified methylalumoxane is provided. |
