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 ((Mw = 7 × 104-2.2 × 106 g mol-1; Mw/Mn = 3.7-33) and regulate isotacticity of polyhexene (content of mmmm pentads from 56% to 96%), while retaining high catalyst activity, are determined.
