Abstract
An aromatic ester containing two azo groups namely p-nitro phenyl azo-b-naphthyl-(4'-azobenzoic acid)-4-benzoate was synthesized by esterfiaction of 4,4'-azo dibenzoic acid with p-nitro phenyl azo-b-naphthol. Synthesized ester was characterized by CHN-elemental analysis, FTIR, 1H NMR and 13C NMR. A modified poly(vinyl alcohol) PVA was obtained by grafting 10 g of PVA-polymer via partial esterification with (2, 3, 4 g) p-nitro phenyl azo-1-naphthyl-4-azobenzoic acid)-4-azo benzoate. Grafting behaviour of PVA-polymer was studied by physical measurements (solubility, swelling), thermal properties (DSC) and tensile strength.
