Interconnected microcellular polymeric monoliths having unexpected high mechanical strength have been prepared using the high internal phase emulsion (HIPE) methodology. Oil-in water concentrated emulsions of aqueous 1-vinyl-5-amino [1,2,3,4]tetrazole (1-VAT) mixed with a low molar ratio (7%) ofN,N0-methylenebisacrylamide as crosslinking agent were prepared using dodecane as dispersed phase and a mixture of hydrophilic surfactants. ''Reverse'' polyHIPE materials were obtained after radical copolymerization, solvent extraction, and drying. Their morphology, chemical composition, and physicochemical behavior are discussed.
