Abstract
This invention relates to a process to polymerize olefins comprising: i) contacting one or more olefins with a catalyst system comprising: 1) a support comprising an organoaluminum treated layered silicate and an inorganic oxide; and 2) a bisphenolate compound; and ii) obtaining olefin polymer having high molecular weight and layered silicate dispersed therein. Preferably the support is in the form of spheroidal particles.
Claims26
A catalyst system comprising:
- 1) support comprising an inorganic oxide and organoaluminum treated layered silicate and 2) bisphenolate compound represented by Formula (A):
- wherein M is a Group 4 transition metal;
- X1 and X2 are, independently, a univalent C1 to C20 hydrocarbyl radical, a C1 to C20 substituted hydrocarbyl radical, a heteroatom or a heteroatom-containing group, or X1 and X2 join together to form a C4 to C62 cyclic or polycyclic ring structure;
- each R1, R2, R3, R4, R5, R6, R7, R8, R9, and R10 is, independently, a hydrogen, a C1 to C40 hydrocarbyl radical, a C1 to C40 substituted hydrocarbyl radical, a heteroatom or a heteroatom-containing group, or two or more of R1 to R10 may independently join together to form a C4 to C62 cyclic or polycyclic ring structure;
- and
- Q is a neutral donor group;
- J is a C7 to C60 fused polycyclic group, which optionally comprises up to 20 atoms from groups 15 and 16, where at least one ring is aromatic and where at least one ring, which may or may not be aromatic, has at least five members;
- G is as defined for J or may be hydrogen, a C1 to C60 hydrocarbyl radical, a C1 to C60 substituted hydrocarbyl radical, a heteroatom or a heteroatom-containing group, or may independently form a C4 to C60 cyclic or polycyclic ring structure with R6, R7, or R8;
- and
- Y is a divalent C1 to C20 hydrocarbylene or divalent C1 to C20 substituted hydrocarbylene.
