Abstract
The present invention provides new catalyst compositions, methods of preparing a catalyst composition, and methods for polymerizing ethylene and other olefins. In one aspect, a catalyst composition comprising an ion-exchangable support such as a pillared clay; a transition metal compound in which the metal has a dn electron configuration, wherein n is greater than or equal to 4 and less than or equal to 8; and an organometal cocatalyst is disclosed.
Claims23
A catalyst composition comprising:
- a) a transition metal compound in which the transition metal has a dn electron configuration, wherein n is greater than or equal to 4 and less than or equal to 8;
- b) a pillared clay;
- and
- c) an organometal cocatalyst.
A process for preparing a catalyst composition, comprising contacting a transition metal compound in which the transition metal has a dn electron configuration, wherein n is greater than or equal to 4 and less than or equal to 8, a pillared clay, and an organometal cocatalyst.
A process of polymerizing olefins in the presence of a catalyst composition, wherein the catalyst composition comprises a transition metal compound in which the transition metal has a dn electron configuration, wherein n is greater than or equal to 4 and less than or equal to 8;
- a pillared clay;
- and an organometal cocatalyst, comprising contacting the catalyst composition with an olefin at a temperature, pressure, and for an amount of time sufficient to polymerize the olefin.
