Abstract

Poly(vinyl chloride) (PVC) has been reacted with 2-amino-5-(phenyl)-1,3,4-thiadiazole(LI), 2-amino-5-(p-nitro phenyl)-1,3,4-thiadiazole(LII), 2-mercapto-5-phenyl 1,3,4-oxadiazole(LIII) and 2-mercapto-5-(p-hydroxy phenyl) 1,3,4-oxadiazole(LIV) in THF to form the modified PVC , which has been characterized by spectroscopic methods. The photostabilization of PVC-L films compounds was investigated, the photostabilization activity of these compounds were determined by monitoring the carbonyl and polyene indices with irradiation time.All results obtained show that the rate of photodegradation of PVC-L films, 30 micrometer in thickness following the trends: PVC> PVC-LIII> PVC-LIV> PVC-LI > PVC-LIIAccording to the experimental results obtained, mechanism were suggested depending on the structure of the PVC-L compounds.
