SYNTHESIS OF LIVING CHAINS OF POLYVINYLPYRIDINE AND THEIR APPLICATIONTO THE CONSTRUCTION OF HOMOPOLYMER AND HYBRID POLYMER WITH COMPLEX ARCHITECTURE

Experimental conditions ensuring the formation of living poly(2- and 4 -vinyl pyridine) chains in the vinyl pyridine - allyl derivatives of c hromium, molybdenum and tungsten systems are described. Variation of t he reagents nature, polarity of the solvent permits to obtain polymers differing in their structural and molecular parameters. Synthesized p olymers contain block and graft sequences, as well as macrocyclic frag ments. Living chains under consideration were applied for polymerizati on of different monomers. Hybrid polymers obtained by this way were st udied in detail by the same methods as the homopolymers.
