The activity and stereospecificity of the catalytic system TiCl4-Et2AlCl of propylene polymerization was studied in relation to the nature of carbon-containing supports like graphite, fullerene C60, anthracene, polyacetylene, and fullerene soot. Graphite and fullerene soot were most effective supports. Isotactic polypropylene was formed at a high rate at definite (transition metal)/support ratios. The active centers of graphite and fullerene soot were shown to be different, the catalytic activity being higher in graphite.
Keywords: stereospecific polymerization of propylene, carbon-containing supports
