| 摘 要： | 采用氧化还原体系合成羟乙基纤维素-丙烯酰胺( HEC-AM)接枝聚合物,利用旋转黏度计对接枝聚合物溶液的增黏性、耐热性、耐盐性等进行测定.结果表明:在所测试的聚合物质量分数(W)范围内,HEC-AM的增黏性要高于纯的聚丙烯酰胺( PAM)；当W( HEC-AM)大于0.8％后,HEC-AM的黏度增长迅速.在同一温度下,HEC-AM溶液黏度均较PAM溶液高,当温度升至80℃时,HEC-AM的黏度保留率为54.4％,PAM的为28％；在80℃下老化5d后,HEC-AM的黏度保留率为53.3％,PAM为22.7％,HEC-AM比PAM具有更好的耐热性和热稳定性.盐溶液的质量浓度提高,HEC-AM和PAM的黏度均降低,但HEC-AM的耐盐性较PAM好；并且在较高温度下,HEC-AM表现出较好的耐盐性.

| Abstract: | Hydroxyethyl cellulose-acrylamide polymer was synthesized by redox,the viscosified property,heat resistance,salt resistance of the graft polymer solution were measured by rotary viscometer.The results showed that the viscosified property of HEC-AM was better than that of pure polyacrylamide(PAM) in the rage of the testing concentrations(w);when w(HEC-AM) was higher than 0.8 %,the viscosity of HEC-AM increased rapidly.At the same temperature,the viscosity of HEC-AM solution was higher than that of the PAM so... |
