| 摘 要： | The copolymerization of six 2-substituted 4-methylene-1, 3-dioxolane with aerylonitrile(AN) gives rise spontaneously to the alternating copolymers by the participation of charge-transfer(CT) complexes. The structures of copolymers was ascertained by their IR, ~1H and ~(13)C NMR spectra, etc.. The electron effect of suhstituents on 2-position of monomer 2 is the most important factor in predicting the reactivity of CT complexes. However the steric effect determines the ring-opening degree of monomer 2. The spontaneous copolymerization mechanism has been discussed.
