CURABLE EPOXY RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a curable epoxy resin composition that provides a cured product with improved flexibility and toughness. SOLUTION: This curable epoxy resin composition comprises a modified polymer (A) in which a rubber is modified with a 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO) derivative containing a nitroxide radical having an epoxy reactive group, an epoxy resin (B) and a curing agent (C) so that the properly subdivided rubber is dispersed into the epoxy resin to be a sea-island structure and result in improved toughness.
