  摘要：

  通过两种不同的三步反应合成了新型N-烷基-N-(磷酸乙基)取代的单、双和三(meth)丙烯酰胺3，并通过红外光谱、1H核磁共振和13C核磁共振光谱、折射率和粘度进行了表征。与羧酸酯相比，磷酸乙基取代的(meth)丙烯酰胺单体显示出改善的水解稳定性。磷酸乙基取代的丙烯酰胺单体具有最高的稳定性。丙烯酰胺的聚合焓范围较大，从-50到-70 kJ·mol-1每个双键，而甲基丙烯酰胺的聚合焓范围为-8.57到-25.1 kJ·mol-1每个双键。根据它们的结构，(meth)丙烯酰胺3对牙釉质和牙本质具有高达19.5 MPa的粘附力。单体3c对两种基质的粘附值最高，分别为15.3 ± 3.4 MPa对牙釉质和18.5 ± 2.3 MPa对牙本质。
