A process for forming a high mol. wt., multi-block copolymer comprising two or more chem. distinguishable segments or blocks comprises polymg. one or more olefin monomers in the presence of a chain shuttling agent and a catalyst compn. comprising two or more olefin polymn. catalysts capable of prepg. polymers having differing chem. or phys. properties under equiv. polymn. conditions, or a catalyst compn. comprising at least one olefin polymn. catalyst contg. multiple active catalyst sites capable of prepg. polymers having differing chem. or phys. properties. Propylene was polymd. using trimethylaluminum shuttling agent in C6F2H4 solvent.
