|Title:||CHLORINATED ORGANIC POLYMERS AS SUPPORTS FOR ZIEGLER-NATTA CATALYSTS|
|Abstract:||Chlorinated organic polymers were prepared, characterized and used as supports for TiCl4. The activity of the new catalysts in the polymerization of ethylene was compared with that observed for TiCl4 supported an non-chlorinated polymers. It was found that the new catalysts have initial activities of up to 4 kg PE/mol Ti . min . bar, but deactivate quickly, probably due to insertion of Ti(III) into the carbon-chlorine bonds. The viscosimetric average molecular weights of the PE produced with the new catalysts are between 300 and 550 kg/mol, in agreement with a short polymerization time.|
