0.30-0.40(3H、m),0.84(1H、m),0.90-1.00(6H、m),1.10(1H、m),1.76-2.02(2H、m),2.32(1H、m),2.58(1H、m),2.81-3.07(4H、m),3.57-4.05(8H、m),4.73-4.90(4H、m),6.50-7.12(6H、m).
実施例2及び4と、比較合成例1~3で得られたそれぞれのベンゾオキサジン化合物について、上記分析方法に従い硬化特性評価及び溶融温度評価を行った。その結果を、表1にまとめて示す。
また、表1に示すとおり、本発明化合物である実施例2の化合物は、比較例化合物A並びに比較例化合物C、及び比較例化合物Bよりも低い温度で溶融することが明らかとなった。本発明の一般式(1)で表される新規のベンゾオキサジン化合物を使用した硬化性樹脂組成物は、その製造や取扱いを低い温度で行えるため、非常に有用である。
実施例2化合物を2時間程度発泡がなくなるまで溶融脱気させ、予備加熱したDMA測定用シリコーン注型板に注型した。その後、乾燥機内(DP32、ヤマト科学株式会社製)にて、175℃で2時間加熱して、その後冷却した。得られた板状の樹脂硬化物をサンドペーパーで表面を研磨することにより硬化物の試験片を作製した。
実施例4化合物を2時間程度発泡がなくなるまで溶融脱気させ、予備加熱したDMA測定用シリコーン注型板に注型した。その後、乾燥機内(DP32、ヤマト科学株式会社製)にて、140℃→150℃→160℃→180℃→200℃/各2時間の条件で加熱して、その後冷却した。得られた板状の樹脂硬化物をサンドペーパーで表面を研磨することにより硬化物の試験片を作製した。
比較例化合物AをDMA測定用シリコーン注型板に充填した。その後、乾燥機内(DP32、ヤマト科学株式会社製)にて、175℃で2時間加熱して、その後冷却した。得られた板状の樹脂硬化物をサンドペーパーで表面を研磨することにより硬化物の試験片を作製した。
上記方法で熱硬化して作成したベンゾオキサジン化合物の試験片を、DMAにより硬化物のガラス転移温度(Tg)を測定した。その結果を表2にまとめて示す。
なお、比較例化合物Bのガラス転移温度(Tg)は、エレクトロニクス実装学会誌、第14巻、第3号、第204~211頁、2011年に記載の数値を示す。
