Mousa Al-Ogaili 2 , Khalid Haneen Abass 3* Abstract Oxide of antimony (III) (Sb2O3) is a type of amphoteric oxide, is used in a variety of applications is a pacifying agent for glasses, ceramics, enamels, catalyst, production of plastic, and the vulcanization of rubber. Polymer blend films were prepared by mixing polyacrylamide (PAAm) and polyethylene glycol (PEG4000), with different contents of Sb2O3 nanoparticles by casting method. The diffusions of Sb2O3 nanoparticles within the mixture were examined using optical microscopy. The optical microscopic images showed that good diffusions of nanoparticles with some agglomerations. The optical characteristics were studied by the Spectrophotometer for ultraviolet and visible light in the range of (200-1100) nm. Most optical properties increased with the increasing of wavelength except for transmittance and energy gaps. The analysis of optical properties is the focus of this paper of (PAAm-PEG-Sb2O3) nanocomposite polymer films and study the (Dispersion energy)Ed, (single oscillator energy)Eo, (static refraction index)n(0), and (Moments) M-1 and M-3 are examples of dispersion parameters. Key Words: Nanocomposite, PAAm, Optical Properties, Dispersion Parameters.

It has many advantageous properties, as in resistance, mechanical characteristics, and price-effectiveness, which make it the polymer of choice for a wide range of applications (Singh et al, 2003). Scientists are working hard to develop high-quality polymer composites for use in modern applications. Polymer composites research is expanding rapidly in a variety of exciting directions (Elf strand et al, 2009). Because they have better properties than original polymers, polymer blends play an important role in the development of new materials (Ibrahim and Kadum, 2010; Al-Jamal et al, 2019; Abass and Hamed, 2020; Abass et al, 2021). The property of the material (internal structure) is one of the key factors and has a direct effect on the synthesized nanocomposites, as the nan-fillers in the matrix and the polymer have a strong interaction penny. In addition, it is important for the stability and scattering of the nan-filler in the polymer matrix. This can significantly improve the properties of polymer nanocomposites (Layek and Nandi, 2014; Jawad et al, 2011). There are two factors that control the mechanical properties of polymers (McCrum and Bucknall, 1997): the first factor is the length of the molecule, which is proportional to n (determining the number of monomers), and proportional to the molecular size, or relative molecular mass.
