Synopsis

A soluble V (acac)3/Al(C2H5)2C1 system was found to polymerize propylene to give a syndiotactic “living” polypropylene having narrow molecular weight distribution \(({\bar M_w}/{\bar M_n} = 1.05 - 1.20)\) at temperatures below -65°C. The coupling reaction between iodine-terminated living polypropylene and monofunctional living polystyrene anion was examined at 50°C and shown to result in the quantitative formation of monodisperse AB block copolymer of propylene and styrene. In addition, sequential polymerization of ethylene and propylene was attempted in the presence of the soluble V (acac)3/Al (C2H5)2Cl system to synthesize block copolymers.
