Abstract
We present a study on aqueous solutions of Poly(Ethylene Oxide) (PEO) with
M-w 3400 by means of Small Angle Neutron Scattering (SANS) and Photon Corre
lation Spectroscopy (PCS). In particular the behaviour of the collective di
ffusion coefficient and gyration radius as a function of concentration and
temperature has been analyzed. The results obtained by the integrated appli
cation of this two techniques give information about the interaction betwee
n the polymeric molecules and between the polymer and the solvent.
