✦ Synopsis

Copolymers including hydroquinone and vinylpyridine units have been prepared by the copolymerization reaction of quinones with vinylpyridines. By-products of these reactions are the homopolymer and the hydroquinone form of the respective quinone. It has been established that in the formation of the copolymers, the weak intermolecular complexes of quinones (Qs) with vinylpyridines (VPs) have an essential contribution. The kinetics of Q copolymerization with VP in the presence of triethylamine has been investigated. The values of the reaction order based on the components, the rate constants and activation energies of the copolymerization processes have been determined. The copolymers prepared are soluble in polar organic solvents, have high reactivity for electron exchange, and possess antioxidant, antihypoxemic and antistatic properties.
