Radical copolymerization of N-(2-hydroxyethyl)carbazolyl acry-late with picryl methacrylate takes place mainly through the inter-monomeric charge transfer complex (CTC) in dioxane solution. When the solvent is 1, 2-dichloroethane, concurrent chain transfer reactions arise. The copolymers obtained are intramolecular CTC. The charge transfer interaction depends on copolymer composition and conformation, and on the copolymerization solvent.
