ABSTRACT:
A process for polymerizing addition polymerizable monomers using titanocenes catalysts/catalyst precursors having a selected symmetry condition under condensed polymerization conditions where the symmetry condition is such that the resulting polymer has varying degrees of tactioselectivity or copolymers having regions of varying degrees of tactioselectivity. Preferred classes of the titanocenes are capable of generating near pure isospecific and syndiospecific polymers in solution or in bulk polymerization conditions.
