摘要：

Viscometry results, in conjunction with earlier light scattering data, revealed anomalously large values of the parameters II = MA2/[eta] and k(s)/[eta] for dilute solutions of high molecular weight poly(ethylene oxide) (PEO) in water at 30-degrees-C. Taken together with unusually large values of rho = R(G)/R(H) and X = S/R(H) for this system, it is concluded that these results may be partly explained by PEO coil draining, but, as suggested in the light scattering study, unusually strong and long-ranged PEO coil-coil interactions in solution were also responsible.
