A short-chain triblock copolymer EO9-DMS7-EO9 was synthesized by couplingreaction of allyl-terminated poly(ethylene oxide) and Si–H-terminatedpoly(dimethylsiloxane). The structure and purity of synthesized copolymer wascarefully characterized. Self-assembly behavior of EO9-DMS7-EO9 triblockcopolymer in water was investigated. And it was found that along with theincrease of copolymer concentration, morphology of self-assembled aggregatestransits from sphere to rod. A plausible understanding of the morphologytransition for the investigated triblock copolymer was proposed
