ABSTRACT:
Olefin polymerization catalysts are described that comprise the reaction product of (a) a metallocene and/or a Ziegler-Natta catalyst compound (TICl.sub.4, etc.,) and (b) a liquid clathrate composition formed from (i) an aluminoxane, (ii) an organic, inorganic or organometallic compound, and (iii) an aromatic solvent. These liquid clathrates are obtained by the reaction, in aromatic solvents, of aluminoxanes such as, methylaluminoxane, with organic, inorganic or organometallic compounds that form stable clathrates with the aluminoxane and the solvent.
