ABSTRACT:
Processes are disclosed relating to modifying clays with an olefinic functionalized surfactant containing a chain end polymerizable double bond, and to treating the thus modified organoclay with an olefin polymerization catalyst precursor, and polymerizing an olefin in the presence of the thus treated organoclay and an organoaluminum cocatalyst.
