Molecular Theory of Relaxation Phenomena in Polymers

Abstract

The development of the molecular theory of configurational relaxation phenomena in polymers is briefly reviewed with the emphasis on the method of generalized diffusion equation and Rouse's model.Various dispersion phenomena in polymeric systems such as of dynamic viscosity, of dynamic Young's modulus and of dynamic bulk modulus are elucidated on the basis of the model theory. The present theoretical situation of the dispersion phenomena in crystalline polymers is also discussed. at University of Pennsylvania Library on April 12, 2015 http://ptps.oxfordjournals.org/ Downloaded from * More precisely [71] = kM(Y, (0.5<a<2) at University of Pennsylvania Library on April 12, 2015 http://ptps.oxfordjournals.org/ Downloaded from -1 1 at

“…Another group of articles is concerned with the molecular theory of the viscous flow of colloidal or highpolymeric systems (6,144,149,160,167,170,206,220,283,300,331,335,348,368,399,442,498,550) and one of the supplements of the Progress of Theoretical Physics contains review articles on this subject (170). The books and articles on rheology mentioned below are also relevant.…”
