外加盐对聚甲基丙烯酸己磺酸钠溶液粘度行为的影响

STUDIES ON VISCOMETRIC BEHAVIOR OF SODIUM SALT OF POLY-6-SULFOHEXYL METHACRYLATE SOLUTIONS IN THE PRESENCE OF ADDED SALTS

在恒定外加盐浓度下,提出了PSSHMA-水体系,外加盐浓度Cs、分子量Mw与特性粘数[η]s之间的关联式:[η]s=[η]∞+Ae^(-BCn_(s)^(n))是当外加盐浓度趋于零时,聚电解质链伸展效应对[η]的贡献,B、n是常数。

On the basis of experimental results,new empirical relationship between the concentrations of added salts,the molecular weight and the intrinsic viscosity of a polyelcctrolytc solution is obtained as follows[η]s=[η]∞+Ae^(-BCn_(s)^(n))
