Abstract
Rheological parameters, i.e., the zero-shear viscosity η0 and the steady-state compliance Je of solutions of four-armed, star-shaped and also of highly branched, comb-shaped polystyrenes were determined with a Weissenberg rheogoniometer. The molecular weight and concentration dependences of the parameters of the samples were compared with those of linear polystyrenes and also those of three-armed, star-shaped polymers, published previously. Emphasis is placed on the discussion of the difference between Je of linear polymers and that of branched polymers.
