New aromatic compounds were prepared by reacting 5,5'-methylene di-anthranilic acid with 4,4'-(diazene-1,2-diyl) dibenzoyl chloride by the well-known classical methods. To prepare compounds to contain an amide, ester, and azo groups as a bonding bridge between them. The synthesized was characterized by CHN, FT-IR, 1HNMR, and 13CNMR spectra. Then, they were reacted with polyvinyl alcohol PVA polymer using cold-warm esterification to prepare new graft polymers. The structures of the composites were determined by FT-IR. Graft polymerization of PVA with new aromatic compounds was a way to prepare important polymeric materials with original physicochemical properties for use in new industrial applications. By testing aromatic derivatives the swelling results of the newly prepared graft polymers were very good, ranging from 3-665%, with a life span of a quarter of an hour to three days. While DSC analysis showed good temperatures in the range of 23.4-289.2°C for the prepared graft polymers.
