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 terpolymer P (AM / NaAA / DiC8AM) of acrylamide, sodium acrylate and a novel twin-tailed hydrophobic monomer N, N-di-n-octylacrylamide was prepared by pre-alkali micellar copolymerization- The structure of the copolymer was confirmed by FTIR and 1H-NMR. The apparent viscosity of the copolymer / surfactant composite aqueous solution was measured. The effects of surfactant type, temperature, electrolyte, shear rate and other factors on the apparent viscosity Effect of viscosity. The apparent viscosities of solutions of P (AM / NaAA / DiC8AM) / SDS and P (AM / NaAA / DiC8AM) / CTAB were obviously higher than that of HPAM copolymer solution. The greater the content of hydrophobic monomers, The greater the apparent viscosity of the solution, and its solution has a certain temperature, salt and shear resistance.
