METHOD FOR POLYMERIZATION OF OLEFIN USING CATALYTIC COMPOSITION Russian patent published in 2004 - IPC

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention describes catalytic compositions that can be used in polymerization processes and comprising metal-containing compound with element of group 15, mixed catalytic compositions comprising metal-containing compound with element of group 15 and the second metal compound that in preferable variant represents metallocene catalyst with bulky ligand, catalytic systems applied and not applied on a carrier based on thereof, and a method for polymerization of olefin (olefins) with their using. Invention represents also polymodal polymer, more preferably bimodal polymer, and its application for different final aims, for example, preparing films, molding articles, in particular, pipes. Invention provides the development of more effective, highly output and economically improved polymerization method resulting to preparing polymers eliciting improved physical and chemical properties.

EFFECT: improved polymerization method.
