摘要：

The viscosities of dilute solutions of poly(p-phenylene terephthalamide), PPTS, in dimethylacetamide, water, and their mixtures were determined. The reduced viscosity plot in dimethylacetamide shows a negative slope. When the water content in the mixed solvent in 90% or higher, there is an upswing in the reduced viscosity values at concentrations below 0.1 g/dL. The latter behavior suggests a ''polyelectrolyte'' effect. However, an association model was found to be able to explain the viscosity behaviors in both solvents. (C) 1995 John Wiley & Sons, Inc.
