MEMBRANE ANIONICHE COSTITUITE DA COPOLIMERI DI (2) O (4)-VINILPIRIDINA CON DIVINILBENZENE O CON MONOMERI VINILICI ALOGENATI.

摘要

Novel membranes for electrochemical cells permeable to anions, fluid impervious and resistant to halogens and acidic and oxidizing environments comprised of copolymers of (1) divinylbenzene or halogenated vinyl monomers and (2) at least one member of the group consisting of 2-vinyl-pyridine and 4-vinylpyridine with the compolymers being optionallyl N-alkylated or N-arylated, processes for preparing the said membranes and electrochemical cells and processes using the said membranes.
