STEREOSPECIFIC POLYMERIZATION OF DIOLEFINS BY h3-ALLYLIC COORDINATION COMPLEXES.

This paper presents the most significant advances made in the understanding of mechanism of stereospecific polymerization and points out the key problems that they still raise. The review is presented under headings - fundamentals of the coordinated specific polymerization of diolefins by Ziegler-Natta catalysts; the stereoregulation of the propagation processes in transition-metals catalyzed polymerization; course of the diolefins coordination polymerization - the different reaction steps; conclusions and problems to be solved.
