Viscosity and longest relaxation time of semi-dilute polymer solutions: II. Theta solvent

M. Adam , M. Delsanti

We present zero shear viscosity and longest relaxation time measurements on semi-dilute solutions in the θ region, as a function of concentration and temperature. Our results cannot be described using scaling laws. We show that viscoelastic properties are governed by two differents lengths.
