SYNTHESIS AND PHOTOSTABILITY STUDY OF SOME MODIFIED POLY(VINYL CHLORIDE) CONTAINING PENDANT BENZOTHIAZOLE AND BENZIMIDOZOLE RING

  The present work consist of two parts:-

Part one:-synthesis and characterization

 Five modified PVC polymers containing benzothiazole and benzimidazole as bending groups in the repeating units were synthesized in this work according to the following:

1-PAA: Reaction of PVC with 2-amino benzothiazole in THF solvent afforded the following modified polymer (PAA)
