Synthesis, characterization and corrosion protection properties of polyN-(p-bromophenyl)-2-methacrylamide- co-glycidyl methacrylate on low nickel stainless steel

摘要: The synthesis of copolymers from different feed ratios N-(p-bromophenyl)-2- methacrylamide (PBPMA) and glycidyl methacrylate (GMA) was achieved by using free radical solution polymerization technique characterized FT-IR, 1 H 13 C NMR spectroscopy. thermal stability the synthesized studied thermogravimetric analysis (TGA) differential scanning calorimetry (DSC). molecular weight copolymer is determined gel permeation chromatography (GPC). corrosion performances low nickel stainless steel specimens dip coated with composition were investigated in 0.5 M 2 SO 4 potentiodynamic polarization electrochemical impedance spectroscopic (EIS) techniques. measurements showed protection efficiency change copolymers. It found that properties are owing to barrier effect polymer layer covered on surfaces. However, it observed mole ratio PBPMA GMA plays a major role protective nature copolymer.
