| 摘 要： | 以丙烯酸十八酯(ODA)为疏水单体,与丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酸(AA)通过自由基共聚法制得长脂肪链改性疏水缔合聚丙烯酰胺(PAMBA),采用红外光谱、X射线衍射对其结构进行了表征,并考察了其耐盐性、耐温性及耐剪切性能。研究发现,PAMBA水溶液中存在强烈的分子间缔合作用。合成的疏水缔合聚丙烯酰胺(PAMBA)具有阴离子磺酸基,因此具有良好的抗盐性。和未改性PAM相比,PAMBA在60℃下能保持较高的表观黏度,其耐温性和耐剪切性能明显提高。

| Abstract: | In order to develop a hydrophobically associating polyacrylamide oil-displacing agent,hydrophobically associating polyacrylamide(PAMBA) modified with long chain fat was prepared by free radical copolymerization with octadecyl acrylate(ODA),acrylamide(AM),2-acrylamido-2-methyl propane sulfonic acid(AMPS),and acrylic acid(AA).Fourier transform infrared spectrometer and X-ray diffraction(XRD) were used to characterize the structure of PAMBA.The salt resistance,temperature resistance and shear resistance of PAMBA were discussed.The results show that there are strongly intermolecular hydrophobically associating interactions in the PAMBA aqueous solution;the synthetic hydrophobically associating polyacrylamide(PAMBA) has good salt resistance.Compared with unmodified PAM,PAMBA maintains higher apparent viscosity at 60 ℃,and the temperature resistance and shear resistance of PAMBA is improved appreciably. |
