合成了新型的大单体4-乙烯苄基辛烷基酚聚氧乙烯醚(VBPOE),并用1H-NMR表征了其分子结构.以丙烯酰胺(AM)为主要原料,引入大单体VBPOE和适量的2-丙烯酰胺基-2-甲基丙磺酸钠(NaAMPS),采用自由基胶束聚合法合成了梳型共聚物PAVA,通过FT-IR和1H-NMR对其分子结构进行了表征.加入少量的VBPOE(摩尔分率为0.5%)时,0.20 g/dL的PAVA于30℃在0.0855 mol/L NaCl溶液中的表现黏度为986.7 mPa·s,表明共聚物具有优良的增粘和抗盐能力;0.15 g/dL的PAVA水溶液在75℃的表观黏度仍达281.2 mPa·s,显示了良好的抗温性能;同时PAVA具有良好的触变性能.
