Title:
EPOXY RESIN, PRODUCTION METHOD, AND EPOXY RESIN COMPOSITION AND CURED OBJECT OBTAINED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2018/180451
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an epoxy resin which is excellent in terms of flowability and curability, gives cured objects having satisfactory moisture resistance and mechanical strength, and is suitable for use in applications such as semiconductor encapsulants and circuit boards; a production method for the epoxy resin; an epoxy resin composition containing the epoxy resin; and a cured object formed from the epoxy resin composition. Specifically, provided are: an epoxy resin (A) which comprises, as a main component, an epoxidized dihydroxybenzene optionally having a C1-8 alkyl group as a substituent on the aromatic ring, characterized by showing a maximum peak when examined by GPC, the maximum peak having an areal proportion of 90% or higher; a production method for the epoxy resin; an epoxy resin composition containing the epoxy resin; and a cured object formed from the epoxy resin composition.
