Beschreibung
Zusammenfassung:	This invention relates to an ion exchange resin for producing bisphenol with high percent conversion and high percent selectivity to bisphenol, especially 4,4' isopropyhdenediphenol, wherein said ion exchange resin comprising aromatic polymer having sulfonic acid group modified with at least one promoter selected from compounds shown in the structure (I), (II), (III), (IV) or its amine salt: wherein R represents hydrocarbon unit with 1 to 6 carbon atoms selected from alkyl group, alkenyl group, alkynyl group, phenyl group, or optionally hydrocarbon containing carbonyl group having 1 to 6 carbon atoms; X represents heteroatom; n is an integer number from 1 to 4.
