図9の過程に従って、コンデンサ及び攪拌機を装着した100mlフラスコに、該当アミノフェノール(aminophenol)、イソプタル酸(isophthalic acid)、ナフトエ酸(naphthoic acid)、ヒドロキシ安息香酸(hydroxybenzoic acid)、ナドイミド安息香酸(nadimide benzoic acid)をモル分子比=2:1:2:2:2の範囲で混合反応して製造された前記化学式5の構造を有する可溶性熱硬化性液晶オリゴマー(数平均分子量7500〜9000)100g及びN−メチル−2−ピロリドン(NMP)25gを入れて、90℃まで徐々に温度を上げながら攪拌して可溶性熱硬化性液晶オリゴマーを溶解した。
市販のプリプレグ(斗山電子1080 glass fiber)を参照例(reference)として使用した。
実施例1の可溶性熱硬化性液晶オリゴマーのみを織りガラス繊維に含浸してプリプレグを製造し、比較例1として使用した。
実施例1で、可溶性熱硬化性液晶オリゴマーとアルコキシド金属化合物のみからなる絶縁層組成物を織りガラス繊維に含浸してプリプレグを製造し、比較例2として使用した。
前記実施例1、参照例、比較例1〜2で製造されたプリプレグを圧縮した後、フィルム状に取得して、TA社TMA Q400を利用して熱的特性と、熱膨張係数(CTE)を測定してその結果を下記表1と図10に示した。測定時に窒素をパージした状態で昇温速度を10℃/minで測定した。低温熱膨張係数は50〜100℃を区間に設定して求めた平均値である。
