PROBLEM TO BE SOLVED: To provide a photodegradation composition using polyrotaxane.SOLUTION: There is provided a photodegradation composition containing polyrotaxane consisting of a cyclic molecule, a main chain penetrating a centrum of the cyclic molecule and a terminal group arranged at both terminals of the main chain for preventing elimination of the cyclic molecule from the main chain, where the terminal group consists of photodegradation group, only the terminal group is separated from the main chain by light irradiation and it is degraded to the cyclic molecule, the main chain and the terminal group which constitute the polyrotaxane.SELECTED DRAWING: Figure 7 |
