摘要：

The rotational diffusion of rod-like polar macromolecules (poly-γ-benzyl-l-glutamate or poly-n-hexylisocyanate) within entangled non polar polymer coils (polystyrene) is studied by dielectric absorption in solution. The dielectric increment as well as the rotatory diffusion constant is studied as a function of molecular weight of both components and increasing concentration of the non-polar polymer as well as the temperature. The classical theory of rotational diffusion is not obeyed if the viscosity of the polystyrene solution is taken as the medium viscosity. An increase in molecular aggregation on polystyrene addition is suspected. © 1979.
