Method of bonding substance to be incorporated into polymer terminal

Abstract

A method of bonding a substance to be incorporated into a free terminal of a water-soluble polymer compound chain, characterized by reacting a reactive functional group present at the free terminal of the water-soluble polymer compound chain which is bonded at a binding terminal thereof in the manner of bristles of a brush onto a surface of a base material; with the substance to be incorporated capable of reacting with the reactive functional group; in the presence of a water-soluble polymer compound which promotes the bonding, is disclosed. According to the method of the present invention, when reactive functional groups present at the terminals of water-soluble polymer compound chains which are bonded in the manner of bristles of a brush on the surface of a base material are reacted with substances to be incorporated capable of reacting with the functional group, the substances can be bonded to the polymer compound terminals at a high efficiency.
