摘要
采用前加碱胶束共聚-共水解法制备了丙烯酰胺、丙烯酸钠和新型孪尾疏水单体N,N-二正辛基丙烯酰胺的三元共聚物P(AM/NaAA/DiC8AM),利用FTIR和1H-NMR确定了共聚物的结构,测定了共聚物/表面活性剂复合体系水溶液的表观粘度,研究了表面活性剂种类、温度、电解质、剪切速率等因素对复合体系溶液表观粘度的影响。P(AM/NaAA/DiC8AM)/SDS和P(AM/NaAA/DiC8AM)/CTAB复合体系的溶液表观粘度与HPAM共聚物溶液相比有明显的提高,疏水单体含量越大,复合体系的溶液表观粘度越大,且其溶液具有一定的耐温、耐盐和抗剪切性。
The acrylamide （ AM ）/sodium acrylate （ NaAA ）/dioctylacrylamide （ DiCs AM ） based terpolymer P （ AM/ NaAA/DiCsAM） has been synthesized by co-hydrolysis with addition of alkali before micellar copolymerization, and a new twin-tailed hydrophobic monomer has been grafted onto the copolymer successfully. The structure of copolymer was characterized using FTIR, ^1H-NMR. The apparent viscosity of the aqueous solution of compound system was measured. The influences of various factors, such as surfactant, temperature, electrolyte and shear rate on apparent viscosity, were investigated in detail. The results show that there are strong hydrophobic interaction between P （AM/NaAA/DiCsAM ） and surfactant. The apparent viscosity of solution of complex system has an obvious enhancement compared with pure polymer. The apparent viscosity of solution of complex is increased as the more hydrophobic monomer contains. The solution has a good thermal stability, salt endurance and shear resistance.
