Title: CHROMIUM-BASED OLEFIN POLYMERIZATION CATALYSTS
Abstract:
This invention relates to a catalyst compound for an olefin polymerization catalyst system represented by formula (I) where each T is independently O, S, or N, each Q is independently C or Si; each R1, R2, and R3 is a substituted C1 to C40 hydrocarbyl group, a C1 to C40 hydrocarbyl group, or a substituted heteroatom, provided that the sum of the molecular volume of R1, R2, and R3 is greater than or equal to two times the molecular volume of an isopropyl group.
