摘要：

An efficient method for preparing beta-hydroxy polystyrene resin is described. Friedel-Crafts alkylation of polystyrene resin with propylene oxide in the presence of a Lewis acid catalyst affored 2-(1-methyl) hydroxyethyl polystyrene (PS-PO), Addition of ethylene oxides to the PS-PO in the presence of base gave PS-g-PEG resins. The resin contained 60-80%(w/w) of PEG and showed excellent stability in highly acidic media. (C) 1997, Elsevier Science Ltd. All rights reserved.
