Abstract

Abstract: Fixmans equation was modified for hydrolyzed polyacrylamide,The constants in theequation were determined.An universal MHS equation relating hydrolysis degree with salt concentration was obtained in the form which is suitable for the ranges of parent molecular weights of 10~5～1.3×10~7, of hydrolysis degrees of 4%～40% and of NaCl concentrations of 0.02～0.5mol·L~(-1)at 30℃.The results from the MHS equation are in good agreement with the experi-ments and the reference data.

摘要： 针对水解聚丙烯酰胺修正了Fixman的聚电解质静电扩张理论式，确定了式中各常数，得到一关联水解度h和盐浓度c_s的通用MHS方程式.经验证该方程有好的精确度和宽的适用范围：30℃，母体相对分子质量10~5～1.3×10~7，水解度4％～40％，NaCl浓度0.02～0.5mol·L~-1.
