A study of configurational topology of active groups for H-bond has been performed together with an analysis of vibrational, diffusional and transport properties of Ethylene Glycol (EG:H-(O-CH[sub 2]-CH[sub 2])-OH), EG Methyl Ether (EGmE:CH[sub 3]-(O-CH[sub 2]-CH[sub 2])-OH) and EG Dimethyl Ether (EGdE:CH[sub 3]-(O-CH[sub 2]-CH[sub 2])OCH[sub 3]) and their mixtures with polymers. Infrared (IR) absorption data in the O-H stretching region show various types of H-bond and their evolution as a function of T. The same systems, mixed with Poly(ethylene Oxide) (PEO:H-(O-CH[sub 2]-CH[sub 2])[sub n]-OH) of different molecular weight, give rise to polymer-monomer interaction effects investigated by viscometry and Photon Correlation Spectroscopy (PCS). © 2000 American Institute of Physics.
