PURPOSE: Provided is an adhesive polymer material having reversible and rapidly changeable adhesive property in the very narrow temperature range, which can be used permanently. CONSTITUTION: The adhesive polymer material is represented by the formula 1, wherein R1 is ethylene oxide, siloxane, or acrylate, R2 is -SO2-, -C(OH)2-, -C(COOH)2-, -C(SH)2-, or -C(NH2)2-, R3 is -CH2-, -CF2-, or a combination thereof, R4 is H or F, a is an integer of 50-500, b is an integer of 1-3, and c is an integer of 3-20. The adhesive polymer material controls a transition point by controlling length of a branched chain.
