ALTERNATING CYCLOPOLYMERIZATION OF ALLYL TRANS-CINNAMATE AND MALEIC-ANHYDRIDE

Some features of the radical copolymerization of allyl cinnamate bifun ctional monomers, containing donor (allyl)-acceptor (beta-phenylacryl) double bonds in the molecule, with maleic anhydride have been reveale d. The kinetic parameters of the reactions, including their complex-fo rmation, cyclization and copolymerization constants, as well as the ra tios of chain growth rates for the participation of monomeric charge-t ransfer complexes and free monomers, are all determined. It has been e stablished that an alternative cyclocopolymerization reaction is reali zed, which is carried out via a complex mechanism with the formation o f macromolecules with unsaturated cycle-linear structures. The synthes ized copolymers show high sensitivity to ultraviolet irradiation, elec tron beams and X-rays, but their negative resists differed, with high lithographic parameters and plasma stability.
