Isoparaffin-olefin alkylation process using a supported perfluorinated polymer catalyst

A liquid phase alkylation process which comprises contacting a C.sub.4 to C.sub.6 isoparaffin or mixtures thereof with an olefin selected from the group consisting of C.sub.2 to C.sub.5 monoolefins or mixtures thereof at a reaction temperature of between about 80.degree. C and about 225.degree. C and with a catalyst composition comprising a solid perfluorinated polymer catalyst supported on an inert porous carrier having an average pore diameter of between about 50 A and about 600 A in a weight ratio of catalyst to support of between about 0.5:100 and about 20:100 wherein said catalyst contains a repeating structure selected from the group of:

• ##STR6## where n is 0, 1 or 2;
• R is a radical selected from the group consisting of fluorine and perfluoroalkyl radicals having from 1 to 10 carbon atoms;
• and X is selected from the group consisting of:
• [O(CF.sub.2).sub.m ], [OCF.sub.2 CFY] or [OCFYCF.sub.2 ]
• where m is an integer from 2 to 10 and Y is a radical selected from the class consisting of fluorine and the trifluoromethyl radical.
