Abstract
Provided is a novel polycarbonate polyol derivative having a terminal amino group. The polycarbonate polyol derivative of the present disclosure is represented by Formula (1) below. In Formula (1), A denotes a group having a polycarbonate skeleton, and n and m are average values and are numbers satisfying n≥2 and n−m>0. The group A in Formula (1) is a group in which all hydroxyl groups are removed from the structural formula of a polycarbonate polyol having a number average molecular weight from 300 to 10000, and preferably includes a group having a repeating unit represented by Formula (a) below.
