NOVELTY - Substituted difluoro-ketone compounds (I) are new.    USE - (I) are useful: as surfactants, adhesives or metal bonding agents; and for making homopolymers or copolymers, which are useful in polymer blend for making an article including a film, membrane, fuel cell, humidification device, electrolyzer, water purification device, battery, or ion exchange resin (all claimed).    ADVANTAGE - (I) exhibit enhanced ion conductivity and provide the articles (preferably fuel cell) having excellent proton conductivity, chemical resistance, low gas cross-over and relatively high electrical resistance.
