Rh-catalysts (i) show unusually high tolerance to the reaction surroundings as well as to functional groups of reactants and products, (ii) they often show a precise control of the configurational structure of formed macromolecules (particularly those of polyvinylenes), (iii) they can be transformed to the living polymerization systems, (iv) they can be anchored on various inorganic and organic supports to give effective heterogeneous catalysts, and (v) they can catalyze reactions in the ionic liquid systems. Rhodium complexes are prevailingly used for a preparation of stereoregular (head-to-tail, cis-transoid) polymers of monosubstituted acetylenes, molecules of which easily adopt the helical conformation in the solid state, some of them even in solutions (e.g., molecules of poly(propiolate)s).
