摘　　要：以4-羟基苯硼酸及甲基丙烯酰氯为原料,在三乙胺的存在下,经过酯化反应得到甲基丙烯酸苯硼酸酯。以AIBN为引发剂进行聚合反应,得到聚甲基丙烯酸苯硼酸酯。通过核磁共振氢谱(1HNMR)和傅立叶红外光谱(FTIR)表征了单体和聚合物的结构,利用DSC分析了聚甲基丙烯酸苯硼酸酯的热力学性质。利用聚甲基丙烯酸苯硼酸酯中的硼羟基与多羟基化合物的相互作用,该聚合物可以用来吸附低浓度的聚乙烯醇溶液中的聚乙烯醇。通过COD值测试,证明聚甲基丙烯酸苯硼酸酯可以与低浓度的PVA溶液相互作用,从而降低PVA溶液的COD值。Phenylboronic acid methacrylate was synthesized by esterification between 4-hydroxyl-phenylboronic acid and methacryloyl chloride at the present of triethylamine. By using zaodiisobutyronitrile as initiator,the relating polymer was obtained. The chemical structures of monomer and polymer were characterized by 1HNMR and Infrared spectra. The thermodynamic property of poly phenylboronic acid methacrylate was analyzed by Differential Scanning Calorimetry（ DSC）. The polymer can be used to treat polyvinyl alcohol solution with low concentration because of the interaction between hydroxyl groups in PVA and B-OH. The result of COD value demonstrates that poly phenylboronic acid methacrylate can interact with PVA solution,COD value decreased.
