| Abstract: | A structure rheological analysis was undertaken with cellulose trinitrates dissolved in ethyl acetate. Empirical scaling laws with molecular mass and concentration were found for the zero shear viscosity ηo and the critical shear rate $ \dot \gamma _C $ at the onset of shear thinning. Values for the apparent chain element A' were calculated from the concentration dependent network strand Me and extrapolated to zero concentration. They were compared with dilute solution data. From the concentration dependence of the mass of network strand Me a network with hindered penetration was inferred. |
