An object of the present invention is to provide an epoxy resin composition which has high flexibility, can be molded to a thin membrane, and can become a noninflammable cured product.
The present invention comprises a polyphenol compound obtained by reacting to condense phenol with bischloromethyl biphenyl or bismethoxymethyl biphenyl, removing unreacted phenol and then reacting with BCMB again, wherein the polyphenol compound has a weight-average molecular weight of 3,000 or more as determined by GPC, and using the polyphenol compound as an agent for curing an epoxy resin.
本发明的目的是提供一种环氧树脂组合物,该组合物具有高柔韧性,可模塑成薄 膜,并可成为不易燃的固化产品。
本发明包括一种多酚化合物,它是通过将苯酚与双氯甲基联苯或双甲氧基甲基联苯反应缩合,除去未反应的苯酚,然后再与 BCMB 反应而得到的,其中多酚化合物经 GPC 测定的重量平均分子量为 3,000 或更高,并将该多酚化合物用作环氧树脂的固化剂。
