A modified polyepoxy compound obtained by etherifying a secondary hydroxyl group of a polyepoxy compound having an alcoholic secondary hydroxyl group, such as a polyepoxy compound obtained by reaction of a bifunctional phenol compound and an epihalohydrin, or a polyepoxy compound obtained by reaction of a bifunctional phenol type epoxy compound and a bifunctional phenol compound, and an epoxy resin composition using the modified polyepoxy compound as the epoxy resin. Further, a modified brominated polyepoxy compound obtained by etherifying a secondary hydroxyl group of a polyepoxy compound having an alcoholic secondary hydroxyl group obtained by reaction of a polyepoxy compound which does not substantially contain a halogen atom and a polyhydric phenol compound having at least one bromine atom directly bonded to an aromatic ring per one molecule, and an epoxy resin composition for semiconductor encapsulation having blended therewith the modified brominated polyepoxy compound as the flame retardant.
一种改性聚环氧化合物,通过醚化具有醇仲羟基的聚环氧化合物(例如通过双官能团苯酚化合物和表卤醇反应得到的聚环氧化合物,或通过双官能团苯酚型环氧化合物和双官能团苯酚化合物反应得到的聚环氧化合物)的仲羟基而得到,以及使用该改性聚环氧化合物作为环氧树脂的环氧树脂组合物。此外,一种改性溴化聚环氧化合物,它是通过将一种聚环氧化合物的仲羟基醚化而得到的,这种聚环氧化合物具有醇性仲羟基,该醇性仲羟基是由一种基本上不含卤素原子的聚环氧化合物和一种每一个分子中至少有一个溴原子直接键合到一个芳香环上的多羟基酚化合物反应而得到的,还有一种用于半导体封装的环氧树脂组合物,其中掺入了该改性溴化聚环氧化合物作为阻燃剂。
