Title:
THERMOSETTING RESIN, PRODUCTION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/204169
Kind Code:
A1
Abstract:
A thermosetting resin which is decomposable after being cured is obtained. A thermosetting resin according to one embodiment of the present invention has, in a main chain, a benzoxazine ring structure which is represented by a specific formula and which includes a trivalent aromatic group derived from a phenol compound (A), a divalent aromatic group derived from an aromatic diamine compound (B1), and a divalent aromatic group derived from an aromatic diamine compound (B2).
