摘要: A fluorinated cation exchange resin catalyst is prepared by contacting a polymer containing pendant acid groups, particularly the radical --SO.sub.3 X with elemental fluorine in the presence of a water-free halogenated hydrocarbon liquid and thereafter converting the resulting pendant --SO.sub.3 X radical to a free acid.
