Photostabilization of polystyrene films by anthraquinones derivatives and their complexes with copper (II)‎, oxovanadium (IV)‎ and nickel (II)‎ ions

الملخص EN

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: 1.

[Bis (1,4-dihydroxyanthraquinone)] Copper (II).

2.

[Bis (1,4-dihydroxyanthraquinone)] Oxovanadium (IV).

3.

[Bis (1,4-dihydroxyanthraquinone)] Nickel (II).

4.

[Bis (1-amino-4-hydroxyanthraquinone)] (Copper (II).

5.

[Bis (1-amino-4-hydroxyanthraquinone)] Oxovanadium (IV).

6.

[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.
