| Abstract | ||
| In the present work the photostabilization of polystyrene film (150 5 µm thickness) has been studied using two anthraquinones, A and B derivative and six complexes of this compounds with three ions, copper (II), oxovanadium (IV) and nickel (II), these are: [Bis (1,4-dihydroxyanthraquinone)] Copper (II). [Bis (1,4-dihydroxyanthraquinone)] Oxovanadium (IV). [Bis (1,4-dihydroxyanthraquinone)] Nickel (II). [Bis (1-amino-4-hydroxyanthraquinone)] (Copper (II). [Bis (1-amino-4-hydroxyanthraquinone)] Oxovanadium (IV). [Bis (1-amino-4-hydroxyanthraquinone)] Nickel (II). All this compounds and complexes were identified by FT-IR and UV-Vis. Spectroscopy. The melting point of these complexes were determined. The degree of photodegradation was monitored by FT-IR and UV-Visible spectroscopy techniques and also by the loss in weight and viscosity. The two anthraquinone derivative and their prepared complexes give a good stabilization with compare with unstabilized polystyrene especially Ni complexes and copper complexes which give a good resistance for degradation than anthraquinones only | ||
