The steady gradient and pulsed gradient spin echo NMR Methods of measuring self-diffusion have for some twenty years been applied to the study of polymers. The methods are briefly described, and the principal results of this research are reviewed in three main areas: diffusion of polymers in the melt and in concentrated solutions, diffusion of polymer in dilute and semidilute solutions, and diffusion...
The objective of this review is to characterize the excimer formation and energy migration processes in aryl vinyl polymers sufficiently well that the excimer probe may be used quantitatively to study polymer structure. One such area of application in which some measure of success has already been achieved is in the analysis of the thermodynamics of multicomponent systems and the kinetics of phase...
This review covers the theory and application of Fourier transform infrared spectroscopy to the characterization of polymers. The basic theory, the sampling techniques and the spectral operations are described. The applications discussed include the study of polymer reactions, polymer structure and dynamic effects.
