The goal of this research was to study some Rheological and optical properties of
poly carbonate in (chloroform and toluene) with different concentrations to know the
physical behavior of this polymer in two solvents at room temperature.It was
determined that the value of polymer solution in these two solvents with different
concentrations and the optical absorption, average viscosity molecular weight
Effective molecular radius. The results have shown that the values of density, (shear,
relative, specific, reduced, original) viscosities, Effective molecular radius and
average viscosity molecular weight, increase with poly carbonate concentration in
two solvents.The results also showed that prepared concentrations density was
significantly influenced by the density of solvents used; this influence was not in the
same magnitude for the rest of measurements and calculations. This may be due to
the dynamic behavior of the polymer in a solvent.
