摘要: 依据高分子溶液理论,建立了水解聚丙烯酰胺盐水溶液零剪切粘度ηo和特性粘数〔η〕间的关系:η_o=0.745十0.634(c_p〔η〕)+0.193(c_p〔η〕)~2+0.921(c_p〔η〕)~3,式中c_p为聚合物溶液的浓度.在聚合物溶液浓度与特性粘数的乘积1~7的范围内.该式和本文(I)报通用MHS方程式联合计算的结果与实验结果吻合良好.

Abstract: A relationship between zero-shear viscosity ηo and intrinsic viscosity〔η〕for hydrolyzed polyacrylamide-salt solution was determined on the basis of the theory of macro-molecular solution in the following form ηo=0.745+0.634(C_p〔η〕)+0.193(c_p〔η〕)~2+0.921 (c_p〔η〕)~3.The results from the equation and the MHS equation in part(I)of this paper are in good agreement with the experimental data in the ranges of c_p〔η〕of 1~7.
