The supported Zeigler-Natta catalyst TiCU/MgCl2 Al(i-Bu)3 have been used to synthesize low molecular weight hydroxyl-tipped ethylene and propylene copolymer in conjunction with diethylzinc (as transfer agent). The funclionality value of the prepolymer were depended on the experimental conditions. The most of functionality was over 70%. Diethyl-zinc was used to control the molecular weight of the prepolymer
in the meantime
the functionality of the prepolymer also be dropped.
