METAL-COMPLEXES AS CATALYSTS OF ALKENE POLYMERIZATION

This review is devoted to the coordination polymerization of alkenes. The emphasis is placed on some distinctive features of the kinetics of alkene polymerization in the presence of metal complexes, on the ster eoregulation mechanism in catalytic systems of different types, and on the nature of stereospecific centers. Problems of the kinetic and ste reoregulation nonuniformity of active centers and the relationships be tween the symmetry of the catalytic complex and the stereoregulation m echanism are discussed.
