Abstract
The effects of poisoning materials on catalytic activity and isospecificity of the supported Ziegler-Natta catalyst were investigated. A minor amount of simple structure of Lewis base, i.e., methanol, acetone, ethyl acetate, was introduced into the catalyst slurry for partial poisoning catalytic active centers. It was found that the variations in deactivation power were in the order of methanol > acetone > ethyl acetate. The kinetic investigation via stopped-flow polymerization showed that poisoning compounds caused a decrease in activity through the reduction of the number of active sites whereas no effect on the degree of isotacticity was observed.
