In this research we had been studied the effect of temperature (30 C, 40C, 50C) on the optical and electrical properties for xanthan cellulose polymer dissolved in water to the concentrations from (0.1-0.5) (gm / ml).

Experimentally we had been measured the refractive index by the refract meter and the electrical conductivity for different temperature and from this two properties we calculated the other optical an electrical properties like the reflectance, turbidity, molar reflectance, polarizibility, critical angle, brawster angle, coefficient of finess.

So the molar conductivity an degree of dissociation the results appeared that all these properties are increasing lineally or exponentially increment with increase of concentration while the critical angle, molar reflectance, molar conductivity and degree of dissociation decreasing with increase concentration.

the effect of temperature we find these properties are decreasing with increase the temperature expect the critical angle, molar conductivity and degree of dissociation were inversely behavior.
