A POROUS, ELECTROLYTE-PERMEABLE DIAPHRAGM, ELECTROLYTIC CELL COMPRISING SAID DIAPHRAGM, USE OF SAID ELECTROLYTIC CELL AND PROCESS FOR THE PREPARATION OF SAID DIAPHRAGM

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.
