【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)和聚氧乙烯醚功能單體(VO實驗室自制)為單體,合成了具有T型結構的兩親丙烯酰胺聚合物。采用紅外光譜、掃描電鏡(SEM)、能譜等測試方法表征T型聚合物結構,并對其耐溫、抗鹽等性能進行了綜合評價。結果表明,反應的最佳條件為w(單體)=20%,w(引發(fā)劑)=0.15%(以單體總質(zhì)量計),反應溫度為42℃,反應時間為6h,單體轉化率82%,相對分子質(zhì)量為8.2×106。該T型聚丙烯酰胺比部分水解聚丙烯酰胺(HPAM)具有更加優(yōu)越的耐溫、抗鹽性能。
[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，
