The present specification relates to a polymer comprising a unit represented by Chemical Formula 1, a monomer represented by Chemical Formula 2, a coating composition comprising the same, an organic light emitting device formed using the same, and a method for manufacturing an organic light emitting device using the same:

##STR00001##

wherein the variables are described herein.

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.

The present disclosure relates to a styrene-based copolymer for an electrode binder of a solid alkaline fuel cell, represented by the following Chemical Formula 1, an electrode binder including the same, and a membrane electrode assembly including the electrode binder. The electrode binder for a solid alkaline fuel cell is obtained by dispersing the styrene-based copolymer for an electrode binder in a mixed solvent of alcohol with water. Thus, even when coating electrode catalyst slurry including the electrode binder directly on an electrolyte membrane, the electrolyte membrane is not damaged so that the quality of a solid alkaline fuel cell using the same may be improved.
