Abstract
This invention provides compositions that are useful for polymerizing at least one monomer into at least one polymer.
Claims25
A process to produce a composition of matter, said process comprising contacting an organometal compound, a solid Lewis acid compound, and an organoaluminum compound to produce said composition,
- wherein said composition consists essentially of a post-contacted organometal compound, a post-contacted solid Lewis acid compound, and optionally, a post-contacted organoaluminum compound, and
- wherein said composition can polymerize ethylene into a polymer with an activity greater than a composition that uses the same organometal compound, and the same organoaluminum compound, but uses untreated Ketjen grade B alumina instead of said solid Lewis acid, and
- wherein said organometal compound has the following general formula
- (X1)(X2)(X3)(X4)M1
- wherein M1 is selected from the group consisting of titanium, zirconium, and hafnium, and
- wherein (X1) is independently selected from the group consisting of cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls, and
- wherein said substituents on said substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls, are selected from the group consisting of aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, and organometallic groups, and hydrogen;
- and
- wherein (X3) and (X4) are independently selected from the group consisting of halides, aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, and organometallic groups, and
- wherein (X2) is selected from the group consisting of Group OMC-I or Group-OMC-II, and
- wherein said organoaluminun compound has the following general formula.
- A1(X5)n(X6)3-n
- wherein (X5) is a hydrocarbyl having from 1-20 carbon atoms, and
- wherein (X6) is a halide, hydride, or alkoxide, and
- wherein “n” is a number from 1 to 3 inclusive.
