摘要: This paper reports the results of a scattering study on aqueous solutions Poly(Ethylene Oxide), PEO, with Molecular Weight Mw 600000 performed by means Small Angle Neutron Scattering, SANS, and Photon Correlation Spectroscopy, PCS. The obtained integrated application these techniques indicate swollen state polymer, i.e. that in investigated temperature range water behaves as good solvent for PEO no evidence aggregation. It clearly emerges unaggregate provides starting reference point clarifying many friction properties such system.
