Abstract EN
This paper involved, preparation of solution poly vinyl alcohol (PVA) in polar solvents ( ethanol , water) from ( 298.15 to 348.15) K under atmospheric pressure.
The effect of temperature on viscosity present experimental was studied for solutions poly vinyl alcohol that obtained from experimental data densities in the same temperature ( 298.15 to 348.15 ) K .
and calculate the activation energy of viscosities for these solutions poly vinyl alcohol from arrhenius equation below : (Ea/RT) Ƞ=Ƞ0 exp ……………………………(1) The values of activation energy of solution poly vinyl alcohol in water was 17.496 J while the values of activation energy of solution poly vinyl alcohol in ethanol was 18.237 J.
The different values of activation energy viscosities of these solution due to intermolecular interaction.
