Abstract

The data on the effect of polymerization temperature of 1-hexene within the 30–70 °C range in the presence of a highly active supported titanium–magnesium catalyst on molecular weight characteristics and microtacticity of polyhexene, with cocatalyst composition being additionally varied (AlEt₃ or Al(i-Bu)₃), in the absence and presence of an external stereoregulating electron-donating compound and hydrogen, are reported. Polymerization conditions, making it possible to specifically regulate molecular weight and molecular weight distribution of polyhexene over a broad range ((M_w = 7 × 10⁴–2.2 × 10⁶ g mol⁻¹; M_w/M_n = 3.7–33) and regulate isotacticity of polyhexene (content of mmmm pentads from 56% to 96%), while retaining high catalyst activity, are determined.
