Techniques for Studying Liquid State Transitions in Polystyreneies with an emphasis on polystyrene are discussed. Instrumental techniques cover the areas of dielectric relaxation, thermal methods, dynamic mechanical relaxation, and computer statistical analysis of tabulated literature data, as well as the spectroscopic methods of Fourier transform infrared and

Dielectric Investigations of Poly(Propylene oxide) in the Liquid Region Above ,, weight range of poly(propylene oxide) investigated by dynamic mechanical methods is much larger (400–1,000,000) than the range studied by dielectric methods (400–4,000). Both the dynamic mechanical and dielectric data have always been presented as a function of frequency or reduced frequency. Diele
