摘　　要：以苯甲酰氯、丙烯酸、N,N-二甲基-1,3-丙二胺和氯乙酸为主要原料,合成了一种甜菜碱型功能单体丙烯酰胺丙基甜菜碱。丙烯酰胺丙基甜菜碱单体、丙烯酰胺、疏水单体进行三元共聚,得到聚甜菜碱型疏水聚合物,对聚合物溶液的抗盐性能进行了评价。结果表明,新型聚甜菜碱型疏水聚合物溶液具有优良的盐增稠性能。Benzoyl chloride, acrylic acid, N, N＇ -dimethyl- 1,3-propanediamine and chloroacetie acid were used to synthesize aerylamidepropyl betaine. Zwitterionie polymer was prepared by ternary eopolymerization of acrylamidepropyl betaine, acrylamide and hydrophobic monomers,the salt resistance of the zwitterionic polymer had been evaluated. The results showed that the zwitterionic polymer had a good salt thickening behaviors.
