A short-chain triblock copolymer EO_9-DMS_7-EO_9 was synthesized by coupling reaction of allyl-terminated poly(ethylene oxide) and Si-H-terminated poly(dimethylsiloxane).The structure and purity of synthesized copolymer was carefully character- ized.Self-assembly behavior of EO_9-DMS~7-EO_9 triblock copolymer in water was investigated.And it was found that along with the increase of copolymer concentration,morphology of self-assembled aggregates transits from sphere to rod.A plausible under- standing of the morphology transition for the investigated triblock copolymer was proposed.
