| 摘 要： | 以生物试剂磷酸烯醇式丙酮酸钾（PEPK）、丙烯酸（AA）为聚合单体，采用Na2S2O8-Na2S2O5氧化还原引发体系进行温和的水溶液聚合反应，通过平行合成得到了a、b、c 3个系列的PEPK-AA共聚物。通过红外光谱（FT-IR）、核磁共振（13C-NMR）以及共聚物分子量的测定，表征了PEPK-AA共聚物的化学结构。热失重分析结果显示，随着PEPK含量在共聚物中的增加，其热稳定性也随之增加。

| Abstract: | Three series (a,b,c) of polyacrylic acid copolymers were parallel synthesized by using bio-reagent potassium phosphoenolpyruvate (PEPK) and acrylic acid (AA) as monomer in mild aqueous solution with Na2S2O8-Na2S2O5 as redox initiating system. The chemical structures of the PEPK-AA copolymers were determined by FT-IR, 13C-NMR and the molecular weight measurment. The PEPK-AA copolymers were characterized by TGA measurement, and the results indicate that the thermal stability of the copolymer was increased with the increasing of amount of PEPK component. |
