Abstract: A series of oxymethylene-linked polyoxyethylene-polyoxypropylene multiblock copolymer were synthesized by condensing CH2Cl2, with poly (ethylene glycol)(PEG), poly(propylene glycol) and telechelic dihydroxy-polystyrene(THPS) in the presene of KOH power. The multiblock copolymers exhibit good emulsifying properties and good phase transfer catalystic properties in Williamson reaction.

Key words: block copolymer, amphiphilic copolymer, emulsion property, phase transfer catalysis
