Abstract:
Catalysts having a higher total capacity and containing fewer organic impurities are provided for condensation, addition and esterification reactions, as well as a process for preparing these catalysts and for use of the catalysts for preparation of bisphenols.

Claim (Index 15):
The process according to  claim 14 , wherein:\n the process further comprises forming the bead polymer by converting monomer droplets of a mixture comprising the at least one monoethylenically unsaturated aromatic compound and the at least one multiethylenically unsaturated compound in the presence of at least one initiator, and in the absence of compounds selected from toluene, ethylbenzene, xylene, cyclohexane, octane, isooctane, decane, dodecane, isododecane, methyl isobutyl ketone, ethyl acetate, butyl acetate, dibutyl phthalate, n-butanol, 4-methyl-2-pentanol, n-octanol, and porogens; the sulphonation comprises a 2 stage sulphonation wherein the sulphonation is commenced in a first reaction step at a first temperature of 90\u00b0 C. to 110\u00b0 C. for 10 min to 60 min, and continued in a second reaction step at a temperature of 120\u00b0 C. to 140\u00b0 C. for 3 hours to 7 hours; the sulphonation is conducted in the absence of a swelling agent; the crosslinked bead polymers is readted with the 2,2\u2032-dimethylthiazolidine at temperatures of 5\u00b0 C. to 80\u00b0 C., and comprises:\n initially charging the sulphonated crosslinked bead polymers; \n inertizing the charged sulphonated crosslinked bead polymers by addition of an inert gas; \n adding the 2,2-dimethylthiazolidine by metered addition and with stirring to the inertized sulphonated crosslinked bead polymers; \n stirring the mixture for 2 h to 6 h to produce a catalyst product; \n adding inertized water to the mixture; and \n introducing inert gas to the mixture, and storing the catalyst product in inert gas.
