摘要： 制备线型和网状N-乙烯基咔唑-丙烯酸甲酯共聚物后,用三氟乙酸汞分别在四氢呋喃(THF)和二氯甲烷中进行汞化反应,得到相应的线型和网状汞代咔唑共聚物。这些共聚物经THF溶解或溶胀后,用氢氧化钠水溶液水解,得到相应的水溶性线型高分子和吸水性网状高分子,憎水性汞代咔唑共聚物在THF中由I2取代汞;亲水性汞代咔唑共聚物在水溶液中由KI3取代汞。汞代咔唑高分子链在不同溶剂中可以产生不同的形态变化。

Abstract: Both linear and cross-linked copolymers of N-vinylcarbazole and methylacrylate were prepared and mercuriated by using mercury trifluoroacetate in THF or dichloromethane. The mercuriated copolymers, both linear and cross-linked, were hydrolyzed with sodium hydroxide in a mixture of water and THF. The hydrolyzed mercury loading linear copolymer was soluhle in water,and the hydrolyzed mercury loading crosslinked copolymer was a water-absorbing polymer. The iodination of the hydrolyzed mercuri ated copolymers was carried out in water with KI3, and the iodination of unhydrolyzed mer curiated copolymers was done in THF with I2. The forms of the hydrolyzed mercuriated polymer chains could be changed in different solvents and the change of the forms could af fect both iodination and fluorescence intensity of the corresponding mercury loading copoly mer.

Key words: Copolymer of N-vinylcarhazole and acrylic acid, Mercuriation, Iodination, Hy drolysis, Fluorescence.
