Abstract
Studies of activity and stereospecificity in polymerizations of propylene and butene-1 with several metal-complex catalysts fixed on a graphite surface are reported. High catalytic activity was observed at a strictly determined Ti: graphite ratio. Maximum stereospecificity is observed at the maximum of catalytic activity. Characterization of the catalyst obtained from the interaction of TiCl 4(C 2H 5) 2AlCl with graphite by Chromatographic, polarographic, X-ray and ESR techniques was directed to the origin of the modifying effect of graphite. These results indicated the formation of stable metal complexes containing Ti compounds with TiC 2H 5 moieties in the sites of crystal-lattice defects. Some electrophysical and mechanical properties of polypropylene-graphite sample are also presented.
