合成例2で得られた比較用液状エポキシ樹脂(x−2)200gをフィルムエバポレーターを用いて、真空度0.2Torrで温度260℃の条件下で分子蒸留して、エポキシ樹脂(X−2)102gを得た。この樹脂は、常温で結晶性を有しつつ液状形態を有し、エポキシ当量は151g/eq.、粘度は,51,000mPa・s、GPC測定での理論構造体含有率は98%、エポキシ当量から算出される繰り返し数の平均値は0.01であることが確認された。
液状エポキシ樹脂(X−1)100部、硬化剤(アミキュアーPN−23、味の素ファインテクノ株式会社製)25部及び添加剤(アエロジル#200、日本アエロジル株式会社製)1部を混合し本発明の1液型エポキシ樹脂組成物を得た。この1液型エポキシ樹脂組成物を用いて流動性と保存安定性の評価を行うと共に、この組成物を100℃で1時間加熱して得られた硬化物の接着性と耐湿性の評価を行った。各評価の方法を下記に示す。また、評価結果を組成物中の各成分の配合量と共に第1表に示す。
