Abstract
Polymerization catalyst compositions are provided as are methods of their preparation. The compositions comprise fatty amines and find advantageous use in olefin polymerization processes. The catalyst composition comprises at least one supported polymerization catalyst wherein the catalyst composition is modified with at least one fatty amine wherein the fatty amine is substantially free of particulate inorganic material.
Claims18
A catalyst composition, comprising at least one supported polymerization catalyst wherein the catalyst composition is modified with at least one fatty amine wherein the at least one fatty amine is substantially free of particulate inorganic material, wherein the at least one supported polymerization catalyst comprises two or more catalyst compounds comprising one or more metallocene compounds and one or more Group 15 containing metal compounds,
- wherein the one or more metallocene compounds is selected from:
- (pentamethylcyclopentadienyl)(propylcyclopentadienyl)MX2,
