| Abstract | ||
| The acrylamide monomer is photopolymerized by aqueous Suspension of TiO2 semiconductor (Anatase) at room temperature and light intensity (medium pressure mercury lamp.) of 19.44 mW/cm2. Several parameters were explored that affected the photopolyerization process in this system, and these are:- 1- TiO2 concentration . 2- Monomer concentration . 3- The effect of Argon and Oxygen gases atmosphere . 4- The temperature elevation from (250C) to (650C) . 5- lrradiation . The produced polymer was characterized by FT-IR spectrum, and the spectra were also performed for both polyacrylamide initiated by TiO2and k2S2O8 free radical photo – initator The complete similarity between the two FT-ir spectra reflects that the polymer is atactic, and the method of polymerization was generally a free radical polymerization. | ||
