摘要: 采用光辅助引发技术,通过水溶液聚合法制备丙烯酰胺(AM)、丙烯酰氧乙基三甲基氯化铵(DAC)和丙烯酸钠(AANa)的共聚物P(AMDACAANa)。考察了m(DAC+AANa)∶m(AM)、引发温度、单体(AM+DAC+AA)质量分数、反应液pH值、硫脲质量分数、偶氮类引发剂质量分数等因素对聚合反应结果的影响,并与传统的引发剂引发聚合结果进行了对比。在m(DAC+AANa)∶m(AM)=15∶85,引发温度20 ℃,单体质量分数32%,pH值6,硫脲质量分数10%,偶氮类引发剂质量分数0010 0%的条件下,得到了溶解时间66 min,特性黏数为1356 dL·g-1的聚合物,并用FTIR对其结构进行了表征。

Abstract: Amphoteric ionic polyacrylamide P(AMDACAANa) was prepared in aqueous solution using acrylamide(AM), acryloyloxyethyl trimethyl ammonium chloride(DAC) and sodium acrylate(AANa) as materials by assistance of photoinitiation. The effects of m(DAC+AANa)∶m(AM ), initiation temperature, monomer(AM+DAC+AA) concentration, pH, dosage of thiourea and the mass fraction of azocompound on the intrinsic viscosity and solubility property of product were studied. And compared the result with the traditional initiator. Under the conditions of m(DAC+AANa)∶m(AM )=15∶85, initiation temperature 20 ℃, monomer concentration 32%, pH=6, the dosage of thiourea 060%, azocompound concentration 0010 0%, the intrinsic viscosity of polymer was 1356 dL·g-1 and the dissolving time was 66 min, the structure of copolymer was characterized by FTIR.

Key words:  photo assisted initiation; acryloyloxyethyl trimethyl ammonium chloride; P(AMDACAANa)
