Olefin polymerization catalysts

摘要

A catalyst composition and method for olefin polymerization are provided. In one aspect, the catalyst composition is represented by the formula alphaabetabgammagMXn wherein M is a metal; X is a halogenated aryloxy group; beta and gamma are groups that each comprise at least one Group 15 atom; alpha is a linking moiety that forms a chemical bond to each of beta and gamma; and a, b, g, and n are each integers from 1 to 4.
