Copolymers of diallyldialkylammonium compounds, anion permoselective membranes based thereon and process for preparing said membranes
TLDR
In this paper, Copolymers including diallyldialkylammonium compounds of the formula: where R1 and R2 are independently selected from the group consisting of lower alkyl, halogen substituted lower alkl and phenyl and X is OH, a halogen or an inorganic or organic anion, alkenyl monomers such as methyl vinyl ketone and halogen containing vinyl monomers, are useful in the preparation of permoselective membranes.Abstract:
