試料 : 樹脂固形分換算で1.0質量%のテトラヒドロフラン溶液をマイクロフィルターでろ過したもの(50μl)
撹拌機が備わったフラスコに、ジヒドロクマリン30質量部、37%ホルムアルデヒド水溶液8.22質量部、パラトルエンスルホン酸1.65質量部を仕込み、室温条件下で窒素を吹き込みながら撹拌した。フラスコを100℃に設定したオイルバスに浸し、1.5時間撹拌を続けた。トルエン30質量部を追加し、ディーンスターク管をセットして、脱水しながら12時間撹拌を続けた。反応混合物を分液ロートへ移し、トルエン100質量部、2ナトリウム1水素リン酸1.48質量部、水31.2質量部を加えた。更に、12%1ナトリウム2水素リン酸水溶液をpHが4になるまで追加して振り混ぜた。水層を棄却した後、前記と同量の水を使用して計5回水洗した。加熱減圧条件下でトルエンを除去し、δ−バレロラクトン骨格含有樹脂(1)30質量部を得た。δ−バレロラクトン骨格含有樹脂(1)のGPCチャート図を図1に示す。δ−バレロラクトン骨格含有樹脂(1)は軟化点53℃のアモルファス状固体であった。GPCチャート図から算出した2核体含有量は43.5%、3核体含有量は25.1%であった。また、全2核体成分中、前記構造式(2−1)又は(2−2)に相当する成分の含有量は40%であった。
温度計、滴下ロート、冷却管、分留管、撹拌器を取り付けたフラスコに、ジヒドロクマリンを300質量部、蒸留水36.5質量部、シュウ酸6質量部を仕込み、室温条件下で窒素を吹き込みながら撹拌した。100℃まで加熱し、37%ホルムアルデヒド水溶液131.5質量部を1時間かけて滴下した。滴下終了後、100℃に維持して1時間撹拌を続けた。次いで、水を留去しながら2時間かけて180℃まで昇温した。減圧条件下で2時間乾燥させ、δ−バレロラクトン骨格含有樹脂脂(2)を得た。δ−バレロラクトン骨格含有樹脂(2)のGPCチャート図を図2に示す。δ−バレロラクトン骨格含有樹脂(2)は軟化点118℃のアモルファス状固体であった。GPCチャート図から算出した2核体含有量は16.5%、3核体含有量は18.6%であった。また、全2核体成分中、前記構造式(2−1)又は(2−2)に相当する成分の含有量40%であった。
・フェノール樹脂:DIC株式会社製「PHENOLITE TD−2090」、フェノールノボラック樹脂、軟化点120℃
・エポキシ樹脂:DIC株式会社製「EPICLON 850−S」、ビスフェノールA型エポキシ樹脂、エポキシ基当量188g/当量
表1に示す割合で各成分を配合し、硬化性組成物を製造した。これについて、下記の要領で各種評価試験を行った。結果を表1に示す。
硬化性組成物を型枠へ入れ、プレス機を用いて150℃で10分間成型した。型枠から成型物を取り出し、175℃で更に5時間硬化させた。硬化後の成形物を5mm×54mm×2.4mmのサイズに切り出し、これを試験片とした。
粘弾性測定装置(レオメトリック社製「固体粘弾性測定装置RSAII」)を用い、レクタンギュラーテンション法、周波数1Hz、昇温温度3℃/分の条件で、室温から280℃まで加熱した。弾性率変化が最大となる(tanδが最も大きい)温度をガラス転移温度として評価した。
先のガラス転移温度(Tg)測定と同様の装置及び条件で試験片を作成した。加熱真空乾燥後、23℃、湿度50%の室内に24時間保管した試験片について、JIS−C−6481に準拠し、アジレント・テクノロジー株式会社製インピーダンス・マテリアル・アナライザ「HP4291B」を用い、空洞共振法にて、1GHz、10GHzでの誘電率および誘電正接を測定し、以下の基準で評価した。
[誘電率]
A:3.0以下 B:3.5以下
[誘電正接]
A:0.020以下 B:0.025以下
C:0.030以下 D:0.035以下
