Abstract

Copolymerizations of ethylene or propylene with butadiene, 1,5-hexadiene or 1,7-octadiene by MgH2/TiCl4-AlEt3 catalyst system were carried out. The effect of diene concentration in the reaction medium for each polymerization system on catalytic activity was observed. The compositions of the obtained copolymers were evaluated and the reactivity ratios were determined. Ethylene-propylene-diene terpolymerizations with the same catalyst system were also investigated.
