Rheological properties of aqueous PVA solutions within a wide concentration range have been examined to select a concentration at which apparent dynamic viscosity is suitable for fiber spinning from solution by the wet process. The rheological properties of PVA solutions containing various quantities of nanosilica and nanohydroxyapatite were assessed. It has been found that an increase in the quantity of both types of nanoadditives from 1 to 5% brings about a decrease in the value of the rheological parameter n and enhances the polymeric character of the fluid. © 2009 Wiley Periodicals, Inc.
