摘要： 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.

摘要： The present invention provides a high-purity arylsulfonic acid amine salt vinyl monomer which is an extremely industrially useful arylsulfonic acid monomer with excellent storage stability and amphiphilic solubility in both water and organic solvents, a simple and practical method for producing the same, a polyarylsulfonic acid amine salt which is a polymer thereof, and a method for producing the same. In the arylsulfonic acid amine salt vinyl monomer, a tertiary amine having 2 or 3 different substituents that each have 1 to 7 carbon atoms and also containing at least one or more of tertiary carbon or quaternary carbon or cyclic skeleton in the structure is applied to an amine moiety thereof, and in addition, a polyarylsulfonic acid amine salt having high purity in terms of sulfonation rate and polymerization conversion rate and a polymer thereof are used.

摘要： A crosslinkable copolymer is provided. The crosslinkable copolymer has pendant cationic nitrogen-containing groups with some, but not all, of these pendant groups further including a (meth)acryloyl group. The (meth)acryloyl groups can react to form a crosslinked copolymer that is ionically conductive. The crosslinked copolymer can be used to provide an anion exchange membrane that can be used in electrochemical cells such as fuel cells, electrolyzers, batteries, and electrodialysis cells.
