Vinyl imidazole (VI) was copolymerized with four silane coupling agents, allyl trimethoxysilane (ATS), γ‐methacryloxypropyl trimethoxysilane (MPS), 3(N‐styrylmethoxyl‐2‐amino‐ethylamino)propyltrimethoxysilane hydrochloride (STS), and vinyl trimethoxysilane (VTS), in benzene at 68°C using azobisisobutyronitrile (AIBN) as an initiator. Fourier transform infrared reflection and absorption spectroscopy (FTIR‐RAS) and scanning electron microscopy (SEM) were applied to the study of the corrosion protection on copper by various silane‐modified poly(vinyl imidazole)(1)s [PVI(1)]s. Four silane‐modified PVI(1)s proved to be good corrosion inhibitors in humid conditions. However, the corrosion protection capability at an elevated temperature of silane‐modified PVI(1)s depended on their thermal stability. Poly(VI‐co‐VTS) showed the best corrosion protection capability at elevated temperature due to its highest thermal stability. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 2585–2595, 1997
