以丙烯酰胺（AM）、丙烯酸（AA）、（1-二甲氨基）-烯丙基磷酸（DMAAPA）和N-烯丙基油酰胺（CON）为原料，制备了一种水溶性磷酸盐共聚物AM/AA /DMAAPA/CON。确定了最佳合成条件：AM∶AA∶DMAAPA∶CON＝69.6∶30.0∶0.2∶0.2（wt％）、pH＝7、引发剂加量为0.2 wt％、单体浓度20 wt％、聚合反应温度40℃。对共聚物进行了IR和NMR表征。该聚合物表现出较好的增粘性、抗剪切、耐温和耐盐性能；0.8 wt％的共聚物溶液防膨率达到80.12％，与1.0 wt％的KCl复配后，防膨率达到96.54％。

A tetra-copolymer of AM/AA/DMAAPA/CON was synthesized using acrylamide (AM),acrylic acid(AA),(1-dimethyl-amino)-allyl phosphoric acid(DMAAPA)and N-allyl base oil amides(CON)as raw materials.The optimum synthetic condition was determined as follows:AM∶AA∶DMAAPA∶CON=69.6∶30.0∶0.2∶0.2(wt%),the appropriate pH was 7,initiator was found to be 0.2 wt%,concentration of monomers was 20 wt%and the temperature was 45℃.The structure of copolymer was confirmed by the results of FT-IR and NMR analysis.The copolymer showed good tackifying ,shear-resistant,temperature-tolerance and salt-resist-ant.The anti-swelling rate was found to be 80.12%for the copolymer in 0.8 wt%solution.When mixed with KCl(1.0 wt%),the anti-swelling rate reached 96.54%.
