【摘要】 采用反相悬浮与非均相水解相结合的方法合成了分子量大于 １０７ 的阴离子聚丙烯酰胺（ＡＰＡＡ）。研究了水解度（ＨＤ）与水解时间及体系 叫的关系、不同水醇比（Ｖ＿水／Ｗ＿醇）条件下 ＨＤ与时间的关系，ＨＤ与温 度的关系，同时研究了ＡＰＡＡ在溶液中的粘性行为，讨论了分子量的 测定方法。更多还原

【Abstract】 A Powdery and rapidly dissolved APAA with Ultra-high mol. -wt. has been prepared by inverse suspension and heterogeneous hydrolysis polymerization. Factors influencing hydrolysis degree （HD ） of PAA,such as pH. temperature. The ratio of V_H2OV_-OHand n_NaOH/n_AM have been studied. Also the viscosity of APAA solution and the methods of ■ measurement have been discussed．更多还原
