【摘要】：以丙烯酸(AA)、丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和聚氧乙烯醚功能单体(VO实验室自制)为单体,合成了具有T型结构的两亲丙烯酰胺聚合物。采用红外光谱、扫描电镜(SEM)、能谱等测试方法表征T型聚合物结构,并对其耐温、抗盐等性能进行了综合评价。结果表明,反应的最佳条件为w(单体)=20%,w(引发剂)=0.15%(以单体总质量计),反应温度为42℃,反应时间为6h,单体转化率82%,相对分子质量为8.2×106。该T型聚丙烯酰胺比部分水解聚丙烯酰胺(HPAM)具有更加优越的耐温、抗盐性能。
[Abstract]:Amphiphilic acrylamide polymers with T-type structure were synthesized by using acrylic acid (AA), acrylamide (AM), 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and polyoxylene ether functional monomer (made in VO laboratory) as monomers. The structure of T-type polymer was characterized by infrared spectroscopy and scanning electron microscope (SEM), spectroscopy, and its temperature resistance and salt resistance were comprehensively evaluated. The results showed that the optimum reaction conditions were w (monomer) = 20%, w (initiator) = 0.15% (based on the total mass of monomer), reaction temperature 42 鈩，
