Abstract: In the present research, the effect oftitanium nanoparticles on optical properties of (PVA-PVAC) has been studied. For this purpose, many samples were prepared with different weight percentages of titanium nanoparticles, the samples were prepared by casting method. The absorption spectrum has been recorded in the wave length range 200-1100 nm, the optical energy gap of the indirect allowed and forbidden transition, absorption coefficient and optical constants, such as (extinction coefficient, refractive index and real and imaginary dielectric constants) have been determined. The optical constants are increase with increasing of titanium nanoparticles concentration, also the energy gap decreased with increasing the weight percentages of titanium nanoparticle.
