ABSTRACT:
A novel catalyst for producing crystalline poly alpha-olefins in excellent yields which coproduces substantially zero percent of low-molecular-weight and amorphous polymers is herein described. This novel catalyst is useful in polymerization techniques which use a solvent or those in which condensed monomer is the liquid phase or those in which polymerization is accomplished using monomer substantially in the vapor phase.
