摘要

PROBLEM TO BE SOLVED: To provide a radiation-decomposable crosslinking agent which has decomposability by a low dose of radiation and can be decomposed at a desired place and desired timing.;SOLUTION: A radiation-decomposable crosslinking agent has a branched chain structure containing a polyethylene glycol chain, has the number of branches in the chain structure of 3 or more, and contains a polymerizable functional group arranged at the terminals of the chain structure, and a disulfide bond arranged between the center of the branch in the chain structure and the polyethylene glycol chain, or between the polyethylene glycol chain and the polymerizable functional group.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
