| 摘 要： | 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,0.20g/dL的PAVA于30℃在0.0855mol/LNaCl溶液中的表观黏度为986.7mPa·s,表明共聚物具有优良的增粘和抗盐能力;0.15g/dL的PAVA水溶液在75℃的表观黏度仍达281.2mPa·s,显示了良好的抗温性能;同时PAVA具有良好的触变性能。

| Abstract: | A novel macromonomer p-vinyl benzyl chloride and polyoxyethylene octylphenol ether(VBPOE) was synthesized,which molecular structure was identified by 1H-NMR.The comb-like acrylamide copolymers(PAVA) were synthesized using acrylamide(AM),VBPOE and sodium-2-acrylamido-2-methylpropane sulphonate(NaAMPS) by micellar free radical copolymerization technique,and the copolymers were characterized with FT-IR and 1H-NMR.When fraction of VBPOE is 0.5%,the apparent viscosity of 0.20 g/dL PAVA in 0.0855 mol/L NaCl solut... |
