摘　　要：用一种氧化还原体系的引发剂,采用水溶液聚合法合成了丙烯酰胺-N-(1,1-二甲基-3-氧代丁基)丙烯酰胺(AM/DAAM)二元共聚物。实验中分别考察了原料中单体配比、反应时间、引发剂用量对共聚物的特性粘数的影响;同时采用定量的方法考察了共聚物的溶解性能。结果表明,当DAAM在共聚物中的摩尔百分含量为33.64%时,聚合物的特性粘数比相同条件下合成的聚丙烯酰胺提高9.9倍;当共聚物中DAAM的含量为15%时,共聚物的溶解速率是相同条件下合成的聚丙烯酰胺的4倍。通过对各种组成共聚物在不同盐溶液中的特性粘数的测定,结果显示该共聚物具有良好的耐盐性能。另外,采用红外光谱、核磁共振氢谱对共聚物进行了定性和定量的表征。AM-DAAM copolymers were synthesized with acrylamide and N-（1,1-dimethyl-3-oxobutyl）amide.The factors influencing on the characteristic viscosity [η] in 1mol/l NaCL aqueous solution at 30 ℃ of AM-DAAM copolymer prepared by radicial initiated copolymerization in aqueous solution are investigated：molar ration of DAAM to AM;concentration of initiator K2S2O8-NaHSO3;and reaction temperature.The AM-DAAM copolymer structure was indentified by characteristic absorption peaks in its IR spectrum and the composition of AM-DAAM copolymer was calculated according to the protions in its 1 H-NMR spectrum and its thermal stability was revealed by thermographic curves.
