SUPPORTED FLUOROCARBONSULFONIC ACID POLYMERS AND AN IMPROVED METHOD FOR THEIR PREPARATION Abstract of the Disclosure This invention discloses improved heterogeneous acid catalysts and a method for preparing these catalysts. A heterogeneous acid catalyst has been prepared by coating a carrier with an aqueous emulsion containing a fluorocarbonsulfonic acid polymer in the sulfonyl fluoride form, removing the excess water, heating to a temperature above the softening point of the polymer for a time, and then converting the polymer to the active sulfonic acid form. The substrate has pores of about 0.1 micrometers or greater and a surface area of about 20 m2/g or less.
