摘要 ： 以荧光染料曙红为pH指示剂、甲基丙烯酸为单体、双甲基丙烯酸一缩二乙二醇酯为交联剂、庚烷为致孔剂，利用高分子聚合技术合成了pH敏感功能聚合物。考察制备pH敏感功能聚合物的影响因素条件及其pH响应行为。曙红染料在聚合物介质中由于极性的减弱，其最大荧光发射波长较在水溶液中红移，表观解离常数增大，对pH的响应区间向酸性方向移动。在最佳实验条件下，pH敏感功能聚合物对pH的响应范围为0～3.0，并且具有较好的可逆性和重现性。

Abstract ：A pH sensitive polymer was prepared by copolymerization of methacrylic acid as monomer, diethylene glycol dimethacrylate as cross-linking reagent, heptane as porogen, and fluorescent dye eosin as indicator. The factors of influence on the preparation, and the character of the pH sensitive polymer for pH were studied. The maximal emission wavelength of eosin was red shifted in the polymer than in solution, the apparent Ka largened, and the dissociation equilibrium of indicator was shifted to acidity direction, because the polarity of polymer diminished. Under the optimal condition, the calibration curve of the pH sensitive polymer covered the range of pH 0-3.0 with good reproduction and reversibility.
Key words ：pH;Functional polymer
