摘要
对用改性壳聚糖功能单体与丙烯酸(AA)和丙烯酰胺(AM)通过自由基聚合制备的改性壳聚糖超支化聚合物(HPDACS)在模拟盐水中的溶液性能进行了深入研究。结果发现HPDACS具有优异的增黏性、耐温抗盐性和剪切稳定性,经过90 d老化后,聚合物的黏度保留率为79.94%,证实了其在提高原油采收率方面的应用潜力。
The solution properties of the modified chitosan hyperbranched polymer(HPDACS)prepared by free radical polymerization of modified chitosan functional monomer with acrylic acid(AA)and acrylamide(AM)in simulated brine were studied.The results showed that HPDACS has excellent thickening ability,temperature resistance,salt resistance and shear resistance.After aging of 90 d at 60℃,the viscosity retention rate of the polymer is 79.94%,it has proved its application potential in enhancing oil recovery.
