Degradable crosslinking agent

Abstract

The purpose of the present invention is to provide a decomposable crosslinking agent having an excellent decomposition rate. The present invention pertains to a degradable crosslinking agent containing a compound represented by formula (1), in which a water-soluble degradation product, which is a carboxylic acid, alcohol, amine or thiol containing Z, having a solubility in water of 30 g / L or more is produced by reaction with an oxidizing agent after crosslinking. In formula (1), n > = 1, k > = 0, m > = 0, p1 > = 1, p2 > = 1, and p3 > = 1. R1, R2, and R3 are each independently a single bond, or a C1-500 hydrocarbon group having or not having a substituent or a heteroatom. Q1, Q2, and Q3 are each independently selected from the group consisting of a hydroxyl group, an amino group, a thiol group, a hydrazide group, a carboxylic acid group, an anhydride group, a vinyl group, an allyl group, an acrylate group, a methacrylate group, a crotonate group, an isoprene group, an acrylamide group, a methacrylamide group, a crotonamido group, an epoxy group, an oxetanyl group, an oxazoline group, an isocyanate group, a carbodiimide group, and a hydroxymethyl group; and one or more reactive functional groups selected from the group consisting of a silanol group, a hydroxysilyl group, and an alkoxysilyl group. A independently of each other is a carbonyl group or a single bond. Z independently represent a divalent or higher group including a siloxane structure, or a C1-500 hydrocarbon group having or not having a heteroatom.
