Study of some physical behavior for polycarbonate in two different solvents at room temperature

Abstract EN

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.
