摘要：

Copolymerization of p-benzoquinone and 9-vinylcarbazole has been firstly realized in the presence of triethylamine in ethanol and pyridine medium. The regularities, compositions and structures of products of this process have been studied. It has been established that the basic reaction product is the copolymer with hydroquinone and 9-vinylcarbazole units. Along with copolymer 5-10% hydroquinone and 15-20% homopolymer of quinone are formed. Molecular weight distribution has been studied by gel-chromatographic method and values of molecular weights ((M) over bar(w) =4120-8010 and (M) over bar n =3960-6400) of copolymers have been determined. The formation of weak intermolecular complexes between p-benzoquinone and 9-vinylcarbazole has been fixed by UV method. Thus, the mechanism of formation of copolymer and side products in interaction of p-benzoquinone and 9-vinylcarbazole has been suggested.
