摘　　要： 以丙烯酰胺 ( AM)、N 乙烯基 2吡咯烷酮 ( VP)和 2丙烯酰胺基 2甲基丙磺酸 ( AMPS)为单体 ,以水为溶剂 ,合成了一系列不同分子量的 AM VP AMPS共聚物。研究了单体浓度、引发剂用量、反应温度、聚合体系 p H值、反应时间对其转化率和共聚物特性粘数的影响 ,AMPS、VP含量与共聚物溶液表观粘度、抗盐性能之间的关系以及共聚物溶液的耐温抗盐性能。 AMVPAMPS copolymers with different molecular weight were prepared by aqueous solution polymerization with AM, VP, and AMPS as comonomers. The effects of the monomer concentration, initiator concentration, reaction temperature, pH value and reaction time on conversion and intrinsic viscosity of the copolymer were discussed. The relationships of composition and apparent viscosity of copolymer aqueous solution, as well as salttolerant property were studied. Tolerances of copolymer solution to high temperature and salt were also studied.
