IMPARTING DECOMPOSABILITY TO POLYMER BY ADDITION OF POLYROTAXANE

To provide a crosslinked product of a polyrotaxane and a polymer that can be decomposed by stimulation.SOLUTION: Provided is a crosslinked product that includes one or more polymer chains and a polyrotaxane including a plurality of cyclic molecules and a chain molecule that penetrates the plurality of cyclic molecules and has blocking groups at both ends that prevent the plurality of cyclic molecules from detaching from the chain molecule and in which the plurality of cyclic molecules are bonded to the one or more polymer chains, and the chain molecule and the blocking groups are bonded via a decomposable bond.SELECTED DRAWING: None 【課題】刺激により分解可能なポリロタキサンとポリマーの架橋体を提供すること。【解決手段】１または複数のポリマー鎖と、複数の環状分子と、前記複数の環状分子を貫通し、かつ両端に前記複数の環状分子の鎖状分子からの脱離を防止する封鎖基を有する鎖状分子とを備えたポリロタキサンであって、前記複数の環状分子が前記１または複数のポリマー鎖と結合されているとともに、前記鎖状分子と前記封鎖基が分解性結合を介して結合されているポリロタキサンと、を備えた架橋体。【選択図】なし
