| 摘 要： | 以丙烯酸（AA）、丙烯酰胺（AM）及甲基丙烯酸-β-羟乙酯（HEMA）为单体，N，N’-亚甲基双丙烯酰胺（NMBA）为交联剂，采用辉光放电等离子体引发溶液聚合法合成了三元共聚耐盐性高吸水树脂（PAA—AM—HEMA）．考察了放电电压、放电时间、交联剂用量、丙烯酸对丙烯酰胺的摩尔比以及丙烯酸中和度等因素对树脂吸盐水率的影响．用红外光谱（FT—IR）和扫描电镜（SEM）对产物进行了表征．结果表明，耐盐性吸水树脂在室温下对蒸馏水和0．9％氯化钠水溶液的吸收量分别为996g·g^-1和82g·g^-1，10min时最大溶胀比为67％，且具有良好的凝胶强度和分散性能．

| Abstract: | Salt-resistant superabsorbent terpolymer is synthesized via solution polymerization initiated by glow discharge electrolysis plasma,in which acrylic acid(AA),acrylamide(AM)and 2-hydroxyethyl methacrylate(HEMA)are used as monomers.The synthetic conditions such as the applied discharge voltage and time,the concentration of crosslinker,the molar ratio of AA to AM and the neutralization degree of AA are also studied.The resulting product is characterized by fourier transform infrared spectroscopy(FT-IR)and scan... |
