A VARIETY of some polymers has been synthesized from the ……reaction of hydroxyquinazoline derivatives and amino quinazoline derivatives with methacrylic acid in the presence of N, N-dicyclo hexyl carbodimide (DCCI). The new monomers was polymerized in dimethyl form amide solution using azobis isobutyronitrile initiator. The new polymers were investigated for the corrosion inhibition properties for mild steel corrosion in Hcl solution. The result of these techniques indicated that the inhibition efficiency increased with the concentration of inhibitor and with decreasing the temperature; some thermodynamic parameters are calculated and explained for the tested systems from the data obtained at different temperatures.
