摘要
以含叔胺基功能单作为还原剂的三元引发体系制备了部分水解聚丙烯酰胺（HPAM），研究了它们在常用的NaCl－H2O和NaNO3－H2O对体系中溶解特性；利用光散射法和粘度法测得一系列不同分子量HPAM的MW和［η］，从而得到高分子量部分水解HPAM在1NNaNO3水溶液中一个新的粘度方程以及第二维利系数A2、均方末端距、扩张因子等表征溶液特性的结构参数。
Polyacrylande of high moedr and part hydrolysis (HPAM) was Synthesizedby the initiajton system of functonal monome containing tertisry anfor group-K2S2O8.The dissolving characterizations of sampls of HPAM in the dilute aqucous sokition ofNaCl and NaNO3 were studied by viscometric method. The wopht average molecular Mw andthe second virinl coefficient A2 werd determined by light scatterin method. The relationshipsamong A2 and other structure parameters with Mw were obtained.
