Development of studies devoted to design of polymer-immobilized catalysts

The state of the art in the field of designing metal-complex catalysts for olefin polymerization immobilized on polymer supports is analyzed. The types of polymers used for binding transition-metal compounds and organoaluminum components and the topochemistry of their distribution and transformations in the course of catalyzed reactions are considered. Polymer-immobilized bimetallic catalysts show promise in the catalysis of the polymerization process in which the key role of a macroligand is to unite active centers of various kinds. It has been shown that, in metallocene and postmetallocene catalysts, the same construction principles of immobilization are preserved as in the case of first-generation metal-complex catalysts. The possibility of isolating and studying active intermediates offered by the polymer support and the effect of immobilization on the molecular design of polymer systems are discussed.
