摘要：
A strong-acid cation exchange resin in acid form is contacted with an alkylcarbamoyl alkylthioester in the presence of water for producing a strong-acid cation exchange resin comprising a plurality of acid groups being partially neutralized with a mercaptoalkylamine. The produced partially neutralized cation exchange resin is useful as a catalyst in a process of producing a bisphenol by reaction of a phenolic compound with a carbonyl compound.
