  • Olefin polymerization catalysts
    Patent number: 7718566
    Abstract: A catalyst composition and method for olefin polymerization are provided. In one aspect, the catalyst composition is represented by the formula ?a?b?gMXn wherein M is a metal; X is a halogenated aryloxy group; ? and ? are groups that each comprise at least one Group 15 atom; ? is a linking moiety that forms a chemical bond to each of ? and ?; and a, b, g, and n are each integers from 1 to 4.
    Type: Grant
    Filed: November 25, 2008
    Date of Patent: May 18, 2010
