High internal phase emulsions were employed to prepare highly porous (up to 80% pore volume) monoliths of poly(glycidyl methacrylate‐co‐ethylenegycol dimethacrylate) by free radical polymerisations of continuous phases of emulsions. Monoliths with cavities approximately 4 µm in diameter and with interconnecting pores approximately 0.7 µm in diameter were obtained. In order to obtain monoliths with ion exchange groups on the surface of pores for chromatography applications, functionalisations with different amines were performed and various reaction conditions tested. FTIR spectroscopy and nitrogen content analysis were used to monitor the functionalisation processes. Monoliths were succesfully functionalised with 1,2‐diaminoethane, 1,4‐diaminobuthane, 1,8‐diaminooctane and tris(diethylamino)amine.
