Abstract

Some features of the radical copolymerization of allyl cinnamate bifunctional monomers, containing donor (allyl)-acceptor (beta-phenylacryl) double bonds in the molecule, with maleic anhydride have been revealed. The kinetic parameters of the reactions, including their complex-formation, cyclization and copolymerization constants, as well as the ratios of chain growth rates for the participation of monomeric charge-transfer complexes and free monomers, are all determined. It has been established that an alternative cyclocopolymerization reaction is realized, which is carried out via a complex mechanism with the formation of macromolecules with unsaturated cycle-linear structures. The synthesized copolymers show high sensitivity to ultraviolet irradiation, electron beams and X-rays, but their negative resists differed, with high lithographic parameters and plasma stability.
