全芳香族ポリエステル。
本発明に係る全芳香族ポリエステルは、必須の構成成分として、下記構成単位(I)、(II)、及び(III)または(IV)からなり、全構成単位に対して構成単位(I)の含有量は60〜85モル%であり、全構成単位に対して構成単位(II)の含有量は12〜40モル%であり、全構成単位に対して構成単位(III)または(IV)の含有量は0.1〜3モル%であり、全構成単位に対して構成単位(I)、(II)、及び(III)または(IV)の合計の含有量は100モル%である。
なお、結晶化熱量とは示差熱量測定において、ポリマーを室温から20℃/分の昇温条件で測定した際に観測される吸熱ピーク温度(Tm1)の観測後、(Tm1+40)℃の温度で2分間保持した後、20℃/分の降温条件で測定した際に観測される発熱ピーク温度のピークより求められる発熱ピークの熱量を指す。
上記の本発明の全芳香族ポリエステルには、使用目的に応じて各種の繊維状、粉粒状、板状の無機及び有機の充填剤を配合することができる。
本発明のポリエステル成形品は、本発明の全芳香族ポリエステル又はポリエステル樹脂組成物を成形してなる。成形方法としては、特に限定されず一般的な成形方法を採用することができる。一般的な成形方法としては、射出成形、押出成形、圧縮成形、ブロー成形、真空成形、発泡成形、回転成形、ガスインジェクション成形、インフレーション成形等の方法を例示することができる。
撹拌機、還流カラム、モノマー投入口、窒素導入口、減圧/流出ラインを備えた重合容器に、以下の原料モノマー、脂肪酸金属塩触媒、アシル化剤を仕込み、窒素置換を開始した。
(I)6−ヒドロキシ−2−ナフトエ酸1.44モル(76モル%)(HNA)
(II)4−ヒドロキシ安息香酸0.44モル(23.3モル%)(HBA)
(III)テレフタル酸0.1モル(0.7モル%)(TA)

原料を仕込んだ後、反応系の温度を140℃に上げ、140℃で2時間反応させた。その後、更に340℃まで4.1時間かけて昇温し、そこから15分かけて10Torr(即ち1330Pa)まで減圧にして、酢酸、過剰の無水酢酸、その他の低沸分を留出させながら重縮合を行った。撹拌トルクが所定の値に達した後、窒素を導入して減圧状態から常圧を経て加圧状態にして、重合容器の下部からポリマーを排出した。
実施例1の全芳香族ポリエステルについて、融点、結晶化温度、結晶化熱量、溶融粘度、熱安定性、及び耐加水分解性の評価を以下の方法で行った。評価結果を表1に示す。
示差走査熱量計(DSC、パーキンエルマー社製)にて、全芳香族ポリエステルを室温から20℃/分の昇温条件で測定した際に観測される吸熱ピーク温度(Tm1)の観測後、(Tm1+40)℃の温度で2分間保持した後、20℃/分の降温条件で室温まで一旦冷却した後、再度、20℃/分の昇温条件で測定した際に観測される吸熱ピークの温度を測定した。
