Abstract:
The refractive index increments of cellulose acetate in acetone are determined for three different concentrations and at ten different temperatures, using light of three different wave lengths. These are determined using Brice Phoenix Differntial Refractometer. The values of slopes of the plots of refractive index invemenis versui temperature are in the range of (2.70x10-4 to 6.32x10-4 deg-1) and are in agreement with the values quoted for general case. These values decrease with the increase in concentration as from good to a poor solvent.
