CATALYST ACTIVATORS, PROCESSES FOR MAKING SAME, AND USE THEREOF IN CATALYSTS AND POLYMERIZATION OF OLEFINS |
摘要 |
Compositions useful for activating catalysts for olefin polymerization are-provided. The compositions are derived from at least: a) compound derived from at least (i) carrier having at least one pair of hydrogen bonded hydroxyl groups, (ii) organoaluminum compound, and (iii) Lewis base, such that each of a majority of aluminum atoms in the organoaluminum compound forms chemical bonds with at least two oxygen atoms from the at least one pair of hydrogen bonded hydroxyl groups; and b) Bronsted acid, wherein the molar ratio of the Bronsted acid to the organoaluminum compound is less than or equal to about 2:1. |
