The viscoelastic properties of concentrated polymer solutions are discussed on the basis of the fixed tube model proposed by de Cennes. It is shown that the steady flow viscosity is proportional to M3, where M is the molecular weight, and that the relaxation spectrum exhibits a hump in the relaxatio
Concentrated solutions of poly(vinyl acetate)/toluene and poly(dimethyl siloxane)/octane were investigated in the polymer volume fraction range 0.08 ~ Β’ ~< 0.5 using small angle X-ray scattering. As the concentration increases the polymer-polymer correlation length deviates increasingly from the pre
