SYNTHESIS AND CHARACTERISTICS OF 9-VINYLADENINE-MALEIMIDE COPOLYMER
9-乙烯基腺嘌呤-顺丁烯二酰亚胺共聚物的合成及其特性的研究

9-vinyladenine was synthesized by a 'simple method, and a new polymer was prepared by copolymerization of 9-vinyladenine with maleimide. By comparing the IR, NMR and UV spectra of this polymer, with those of polyvinyladenine and polymalei-mide, it clearly shows that it is a copolymer having hydrogen bonds between molecular chains. This copolymer has the same UV absorption as nucleic acid.
