  • Modifiers for improved olefin polymerization with activated neutral aluminum compounds
    Patent number: 6689852
    Abstract: The present invention is for a transition metal-free catalyst system for synthesizing high molecular weight, linear polymers. The system comprises a catalyst composition having: (a) a neutral compound having the formula AlR3, wherein R is an alkyl or hydride group; (b) a Lewis acid or Lewis acid derivative cocatalyst different from the neutral compound, wherein the cocatalyst reacts with the neutral compound to form an initiator; and (c) an activity-enhancing modifier, wherein the modifier reacts with the initiator to form the catalyst composition. The instant invention is also directed to a method for polymerizing at least one olefinic monomer comprising the step of contacting a feed containing the olefinic monomer under polymerization conditions with the transition metal-free catalyst composition.
