Abstract

Polyacrylic acid has been utilized to react with a variety of substances to create novel compounds with biological activity because it is a recognized safe material to work with. In this work, the AB chemical was created by reacting polyacrylic acid with benzidine. It was then combined with a class of cyclic aldehydes to create novel Schiff-base compounds with biological advantages. FT-IR and 1H-NMR spectroscopy were used to characterize them. Their melting point, solubility in various solvents, viscosity, and biological activity against gram-positive and gram-negative bacteria were all measured. Each sample's antioxidant activity was assessed and compared to ascorbic acid.
