摘要: A catalyst for the preparation of bisphenols from phenols and compounds containing carbonyl groups consisting of a styrene/divinyl benzene copolymer into which are introduced sulphochloride groups which, in turn, have been partly reacted with mercaptoalkylamine and partly hydrolyzed to form sulphonic acid groups.
