    Abstract: A method is provided for obtaining crosslinked polymers, particularly fluorinated polymers having pendent sulfonic acid groups, by crosslinking through pendent groups which include a sulfonyl chloride group (—SO2Cl). The sulfonyl chloride group may be removed by application of electromagnetic radiation, typically in the ultraviolet band, or a radical initiator, leaving behind a radical which readily binds covalently to other polymer strands or to crosslinking agents to form crosslinks. Typically, the polymer is made by providing a polymer comprising pendent groups which include a group according to the formula —SO2F and converting at least a portion of the —SO2F groups to —SO2Cl. After crosslinking, the remaining —SO2F groups may be converted to sulfonic acid groups, yielding a crosslinked polymer electrolyte. Such crosslinked polymer electrolytes may be used to make polymer electrolyte membranes (PEM's) that may be used in electrolytic cells such as fuel cells.

    Abstract: A hard coating composition for use as a stain repellent single layer on an optical display. The coating composition adds a monomer of a mono or multi(methyl)acrylate bearing at least one monovalent hexafluoropolypropylene oxide derivative and a free radically reactive compatibilizer consisting of either a fluoroalkyl-group containing acrylate compatibilizer or a fluoroalkylene-group containing acrylate compatibilizer to a conventional hydrocarbon-based hard coat formulation. The resultant coating is substantially smooth and forms a durable surface layer that has low surface energy that is stain and ink repellent.
