Study of alternating copolymerization of piperylene and ethylene in presence of complex organometal catalysts

The authors have studied the alternating copolymerization of piperylene and ethylene under the influence of the catalytic systems TiCl4CH3COC6H5(iso-C4H9)3Al and [(CH3)3SiO]VOCl2(iso-C4H9)3Al. It was established that both catalytic systems give alternating copolymers of piperylene with ethylene consisting to 53–73% of 1,4-trans units and to 27–47% of 1,2-trans units.
