ABSTRACT:
The present invention relates to a modified epoxy resin, a method for the preparation thereof and an epoxy resin composition using the modified epoxy resin. In particular, it relates to a modified epoxy resin of the general formula (I) which is prepared by incorporating a monomaleimide having a carboxy group useful as a heat resistance-improving agent of a resin composition containing an epoxy resin and maleimides into an epoxy resin, and an epoxy resin composition for sealing a semiconductor element having the improved heat resistance and moldability by the modified epoxy resin. ##STR1## wherein, R represents a hydrogen atom or an alkyl group having from 1 to 10 carbon atoms (C.sub.1 to C.sub.10), and
