Experimental and theoretical studies of polymer/solvent viscosity mixtures

چکیده مقاله

Viscosity of the binary mixtures of poly- mers/solvent: (polystyrene/toluene), (polymethylmethac- rylate/acetone), (polystyrene/benzene), (polystyrene/cy- clohexane), and (polymethylmethacrylate/chloroform) were measured at different temperatures by a Haake viscometer. The samples of polymer/solvents mixtures used in the vis- cometry measurements were in low concentration of poly- mer (maximum concentration 0.25 g/cm3). The measured viscosities were used to evaluate the parameters of the mod- ified Eyring’s viscosity equation.
