✦ Synopsis
A technique useful for estimating the viscoelastic properties of dilute solution poly(ethy1ene oxide) was developed. With this technique, the effects of concentration, shear rate, presence of salt and/or anionic surfactant, and molecular weight on the viscoelastic properties in dilute solution were determined. Differences in the viscoelastic properties of commercial grade materials were observed. An explanation for the differences in salt and surfactant solutions based on formation of a weak ionic network is presented.
