Abstract
Disclosed are a carbonate group-modified epoxy resin in which carbonate groups are introduced into an epoxy resin having secondary hydroxyl groups at terminals or lactone-modified epoxy resin having primary hydroxyl groups at terminals by the ring-opening reaction of a cyclic alkylene carbonate, a process for the preparation thereof, and a thermosetting resin composition containing the carbonate group-modified epoxy resin.
