Polymerization of propylene by Cp\*TiMe 2 (-Me)B(C 6 F 5 ) 3 in the presence of increasing partial pressures of H 2 results in ever decreasing polymer molecular weights, which is consistent with the hydrogenolytic chain transfer processes involving metal-polymer bonds in many heterogeneous and homog
