A cationic copolymer comprises the divalent monomer units: wherein: each Ar.sup.1 independently represents phenylene; each L independently represents a direct bond or wherein each R.sup.1 independently represents an alkyl group having 1 to 4 carbon atoms, and each R.sup.2 independently represents an alkylene group having from 1 to 6 carbon atoms, and each Z.sup.− represents a non-interfering anion; each Ar.sup.2 independently represents an optionally substituted divalent aryl ring, with the proviso that if L represents a direct bond, then Ar.sup.2 represents an optionally substituted cationic divalent aryl ring accompanied by Z; each R.sup.3 independently represents H or an alkyl group having 1 to 6 carbon atoms; and each D independently represents a direct bond or Ar.sup.2, wherein adjacent D and L are not both direct bonds, and wherein if L is a direct bond, then D is Ar.sup.2. The cationic copolymer can be free-radially cured and used in a membrane.

A bipolar membrane in which a cation-exchange membrane and an anion-exchange membrane are joined to each other, wherein a leakage ratio of gluconic acid at 60° C. is not more than 1.0%, and the cation-exchange membrane is supported by a polyolefin reinforcing member and, further, contains a polyvinyl chloride.

An anion exchange membrane is composed of a copolymer of 1,1-diphenylethylene and one or more styrene monomers, such as 4-tert-butylstyrene. The copolymer includes a backbone substituted with a plurality of ionic groups coupled to phenyl groups on the backbone via hydrocarbyl tethers between about 1 and about 7 carbons in length. High-temperature conditions enabled by these copolymers enhance conductivity performance, making them particularly suitable for use in anion exchange membranes in fuel cells, electrolyzers employing hydrogen, ion separations, etc. The properties of the membranes can be tuned via the degree of functionalization of the phenyl groups and selection of the functional groups, such as quaternary ammonium groups. Several processes can be used to incorporate the desired ionic functional groups into the polymers, such as chloromethylation, radical bromination, Friedel-Crafts acylation and alkylation, sulfonation followed by amination, or combinations thereof.
