摘　　要：水解型聚丙烯酰胺 (HPAM)通过化学接枝反应在其大分子亲水主链上引入少量的十六碳疏水基团的支链 ,得到一种疏水基改性的接枝共聚物———水解型聚丙烯酰胺接枝十六醇(HPAM -g-HDO)。流变性能测定表明 ,HPAM -g-HDO的抗盐、抗剪切等性能较HPAM有明显提高 ,是一种性能优异的驱油用增稠剂。A new graft copolymer,hydrolyzed polyacrylamide graft hexadecanol(HPAM-g-HDO),was synthesized by chemical grafting reaction, which introduced hexadecyl side chain onto the main chain of hydrolyzed polyarcylamide(HPAM). Rheological behavior of HPAM-g-HDO was determined by rotational viscometers. The results showed that the properties of salt resistance and shearing resistance of HPAM-g-HDO were improved obviously compared with HPAM. It could be used as a thickener for oil-displacing.
