الملخص العربي
An aromatic ester containing two azo groups namely p-nitro phenyl azo-β- naphthyl-(4'-azobenzoic acid)-4- benzoate was synthesized by esterfiaction of 4,4ʹ- azo dibenzoic acid with p-nitro phenyl azo -β-naphthol. Synthesized ester was characterized by CHN –Elemental analysis, FTIR, 1H-NMR and 13C-NMR. A modified PVA polymer was obtained by grafting 10 gm of PVA- polymer via partial esterification with (2, 3, 4) gm p-nitro phenyl azo-1- naphthyl-4-azobenzoic acid)-4-azo benzoate. Grafting PVA- polymer behaviors was studied, by physical measurements (solubility, swelling), thermal properties (DSC) and tensile.
