Novel biphenyl-based photo-cross-linkable polymers were synthesized and characterized by nuclear magnetic resonance and Fourier transform infrared spectroscopy. Upon UV irradiation, the polymers were cross-linked even in the absence of photo initiator or sensitizers, and the rate of photo-cross-linking was examined and discussed. The effectiveness of both virgin and cross-linked polymers for corrosion resistance on mild steel in 1.0 M hydrochloric acid medium was investigated, using polarization studies, electrochemical impedance measurements as well as by adsorption isotherm and surface analysis. The results clearly indicated a dramatic increase in the efficiency of inhibition of corrosion on mild steel by the photo-cross-linked polymer as compared to virgin polymers.
