Abstract

Membrane semiperméable composite comprenant un support poreux et un feuil mince réticulé formé à la surface de celui-ci. Le feuil mince réticulé a été préparé par réaction d'un composé A, d'un composé B et d'un compose C, le composé A étant une polyalkylène-imine, le composé B une pipérazine, une (amino-alkyl)-2, -3 ou -4 pipéridine ou une poly-alkylène-imine autre que A, par exemple le tétraza-1,4,8,11 cyclotétradécane, et le composé C un composé renfermant deux ou plus de deux groupes fonctionnels capables de réagir avec des groupes amino, tel que le chlorure d'isophtaloyle, le chlorure de téréphtaloyle ou un di-isocyanato-toluène. Application à l'osmose inverse et à l'ultrafiltration, par exemple pour la désalinisation d'eaux saumâtres ou d'eau de mer.
