Abstract: front page image
(EN)An epoxy resin having a structure of hydrogenated epoxy resin which contains a naphthalene ring is disclosed. This epoxy resin is represented by the general formula (1): (wherein n is 0-15, G represents a glycidyl group, and at least one ring A in a condensed ring composed of two rings A represents an aliphatic ring), and is obtained by hydrogenating a corresponding aromatic epoxy resin so that the hydrogenation rate of naphthalene ring is within 10-100%. This epoxy resin is excellent in workability since it is liquid at room temperature or solid with a low melting point, and thus is suitably used as a semiconductor sealing material, a casting material, an electric insulating material and the like.
(FR)L'invention porte sur une résine époxyde du type hydrogénée, contenant un cycle naphtalène, et de formule (I) dans laquelle: n est 0 15, G représente un groupe glycidyle; et au moins l'un des cycles A d'un cycle condensé en comprenant deux est un cycle aliphatique. Ladite résine, obtenue par hydrogénation d'une résine époxyde aromatique correspondante pour que le taux d'hydrogénation du cycle naphtalène soit compris entre 10 et 100%, présente une excellente ouvrabilité, car liquide à la température ambiante ou solide et à bas point de fusion; elle peut servir de matériau de scellage pour semi-conducteurs, de matériau pour moulages, d'isolant électrique etc.
