Title:
EASILY DISINTEGRABLE ADHESIVE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/225167
Kind Code:
A1
Abstract:
This easily disintegrable adhesive material contains a thermosetting hyperbranched polymer (P) and a disintegration-imparting agent (Q). The thermosetting hyperbranched polymer (P) is a dual curing type thermosetting hyperbranched polymer (P) which contains an ethylenically unsaturated double bond positioned at a side chain terminal as a first thermosetting group and has a second thermosetting group that is different from the first thermosetting group. The disintegration-imparting agent (Q) contains one or both of a compound (q1) having, in the molecule, two or more reactive groups that react with the second thermosetting group, and a catalyst compound (q2) that facilitates a reaction between the second thermosetting groups.
