Copolymerization of ethylene with propylene and hexene-1 initiated by Zr(BH4)4 and Hf(BH4)4 catalysts supported on silica gel and alumina, respectively, was studied. Data on the reactivity ratios r1 were obtained. The reactivity of these systems in copolymerization significantly depended on the nature of the support and was not affected not by the nature of the transition metal. The catalyst Zr(BH4)4/SiO2 showed very high activity in copolymerization (r1 was 4.4 and 18.2 for propylene and hexene-1, resp.). Copolymers prepared using this catalyst showed compositional. heterogeneity. Molecular structure and microstructure of the copolymers were studied. High content of the inverse propylene units due to low regiospecificity of the Zr(BH4)4/SiO2 catalysts was found.
