The study it includes the recording of the spectrum of absorbance and transmittance for (PEO) solutions and the blend solution (PEO – PEG) , at the temperature (30 ºC). and calculating the absorption coefficient and other optical constants. These samples have been prepared in different weight concentrations (0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8 g/mL) % as solution for (PEO),then the additives added as (0.25 g ) and ( 0.5 g) of (PEG)respectively, also samples prepared by liquids mixing method before and after adding (PEG) polymer. Optical properties such as ( absorbance and refractive index ) have been measured, then from those properties other properties were calculated such as (transmittance, reflectance, absorption coefficient of electromagnetic waves, natural lifetime, coefficient of fineness, molar reflectance, critical angle and Brewster angle ). All those properties have been measured for two cases before and after addition at temperature (30 ºC).
