セイコーインスツルメンツ株式会社製Exstar6000を用いて測定を行った。液晶ポリエステル樹脂試料を、室温から20℃/分の昇温条件下で測定し、吸熱ピーク温度(Tm1)を観測した後、Tm1より20〜50℃高い温度で10分間保持する。次いで20℃/分の降温条件で室温まで試料を冷却した後に、再度20℃/分の昇温条件で測定した際の吸熱ピークを観測し、そのピークトップを示す温度を液晶ポリエステル樹脂の結晶融解温度とする。
型締め圧15tの射出成形機(住友重機械工業(株)製MINIMAT M26/15)を用いて結晶融解温度+20〜40℃のシリンダー温度、金型温度70℃で射出成形し、短冊状曲げ試験片(長さ65mm×幅12.7mm×厚さ2.0mm)を作製した。曲げ試験は、3点曲げ試験をINSTRON5567(インストロンジャパンカンパニイリミティッド社製万能試験機)を用いて、スパン間距離40.0mm、圧縮速度1.3mm/分で行った。
トルクメーター付き攪拌装置および留出管を備えた反応容器にPOB、BON6、BPNDAおよびTPAを、表1に示す組成比で、総量6.5モルとなるように仕込み、さらに全モノマーの水酸基量(モル)に対して1.03倍モルの無水酢酸を仕込み、次の条件で脱酢酸重合を行った。
また、曲げ強度および曲げ弾性率も高い数値を示し、機械的性質にも優れるものであった。
モノマー組成比を、表1に示す組成比に変えることの他は、実施例1と同様にして、液晶ポリエステル樹脂のペレットを得た。重合時の酢酸留出量は、ほぼ理論値どおりであった。
モノマー組成比を、表1に示す組成比に変えることの他は、実施例1と同様にして、液晶ポリエステル樹脂のペレットを得た。重合時の酢酸留出量は、ほぼ理論値どおりであった。
