Abstract
Crosslinked polymers are produced by polymerizing a styrene-based comonomer with a bifunctional styrenated crosslinkable monomer comprising the following straight chain formula: CH═CH—CH—CH—(OCHCH)—O—CH—CH—CH═CH. The styrenated crosslinkable monomer can be produced from a two arm polyethylene glycol having a molecular weight between 200 g/mol and 35,000 g/mol. The styrenated crosslinkable monomer can also be produced from a two arm polyethylene oxide having a molecular weight between 100 kg/mol and 800 kg/mol. The styrenated crosslinkable monomer can also be produced from a four arm polyethylene glycol. Polymer electrolyte membranes are produced from the crosslinked polymers.
