In this work  micelles are formed by gradient copolymer of styrene and methyl methacrylate in acetone-water mixture and their temperature responsiveness is investigated in a narrow range near room temperature. Three different kinds of structural transitions could be induced by temperature: unimers to micelle transition  shrinkage/stretching of micelles  and morphological transition from spherical micelles to vesicles. In addition  a model analysis on the interface of gradient copolymer micelle is made to better understand these phenomena. It is found that both position and composition of the interface could alter in response to the change in temperature. According to the experiments and model analysis  it is proposed that temperature responsiveness might be an intrinsic and universal property of gradient copolymer micelles  which only originates from the gradient structure.
