Description
Summary:A study has been made of the inhibitive action of carbon monoxide during ethylene polymerization on the catalytic systems dicyclopentadienyltitanium dichloride-dimethylaluminium chloride, diacetylacetonatetitanium dichloride-thylaluminium chloride, vanadium triacetylacetonate-diisobutylaluminium chloride. At low concentrations of CO there is a reversible process of inhibition of catalytic activity. The concentration of carbonyl groups found in the polymers after a re-polymerization has been carried out is significantly higher. The inhibitive action of CO is due not only to its incorporation via the active Me-C bond, but is also largely the result of its coordination.
