Summary
We show that the hydrodynamic radius of Poly(ethyleneoxide) macromolecules may be very different in water and water-isopropanol mixture (90%/10%). This dimension is a function of the age of the solution in pure water. The influence of the solvent and the age (i.e. of the hydrodynamic radius-) on the properties in laminar and turbulent flows is studied.
