## Abstract Copolymerization of heptaโ1,6โdiene with ethylene using a cobaltโbis(imino)pyridine complex affords a polymer that contains __trans__โ1,2โfiveโmembered rings in the repeating unit from heptaโ1,6โdiene. The ratio of the repeating units of diene to those of ethylene is controlled from 3:
## Abstract Summary: The bis(imino)pyridyl vanadium(III) complex [VCl~3~{2,6โbis[(2,6โ__i__Pr~2~C~6~H~3~)N๏ฃพC(Me)]~2~(C~5~H~3~N)}] activated with different aluminium cocatalysts (AlEt~2~Cl, Al~2~Et~3~Cl~3~, MAO) promotes chemoselective 1,4โpolymerization of butadiene with activity values higher than
## Abstract The effect of various alkylaluminium compounds and their mixtures on ethylene polymerization catalyzed with a tridentate bis(imino)pyridinyliron catalyst is studied. Triethylaluminium and trihexylaluminium are good cocatalysts but yield polyethylenes with broad molar mass distribution (
