The photo sensitized degradation of polymer system is occasionally used as a means of
solving the problem of environmental pollution, photostabilization of polystyrene films
using chrom complexes was investigated. Poly styrene films with a thickness of 80μm
and contains complexes concentration of 0.05% wt were produced by the casting
method with chloroform being the solvent The photostabilization activities of these
complexes were determined by monitoring changes in carbonyl,(I CO ) and hydroxyl,(I OH )
indices and calculating the photodecomposition rate constant (k d ), the average molecular
weight for the studied films The results obtained showed that the photostabilization
activity of polystyrene film in the presence of the complexes as additive follows the
trends:
Cr [S2CN(C 2 H 5 ) 2 ] 3 > Cr[C 6 H 4 NO 2 ] 3 > PS > Cr(acac)
