摘要： Bifunctional styrenated crosslinkable monomers are produced by functionalizing a linear chain diol with styrene, the linear chain diol being a diol with linear chain fluorinated segments or a linear chain hydrocarbon diol. Crosslinked polymers are produced by polymerizing the styrene-based comonomer with the bifunctional styrenated crosslinkable monomers. Polymer electrolyte membranes are produced from the crosslinked polymers. Crosslinking a bifunctional fluorinated monomer with a sulfonic acid bearing comonomer produces crosslinked polymers and membranes there from with very high acid content and strong polymer structure.
