本発明の環式ポリフェニレンエーテルエーテルケトン組成物の製造方法としては、上記した特徴を有する環式ポリフェニレンエーテルエーテルケトン組成物を製造できれば如何なる方法でも問題ないが、好ましい方法として(a)少なくともジハロゲン化芳香族ケトン化合物、ジヒドロキシ芳香族化合物、塩基(A)、および有機極性溶媒を含む混合物(ア)を加熱して反応させることによる製造方法、(b)少なくとも線状ポリフェニレンエーテルエーテルケトン、ジハロゲン化芳香族ケトン化合物、ジヒドロキシ芳香族化合物、塩基(A)および有機極性溶媒を含む混合物(イ)を加熱して反応させることによる製造方法、(c)少なくとも線状ポリフェニレンエーテルエーテルケトン、塩基性化合物(B)、有機極性溶媒を含む混合物(ウ)を加熱して反応させることによる製造方法を用いることが強く望まれる。以下、これら環式ポリフェニレンエーテルエーテルケトンの好ましい製造方法につき詳細を記す。
環式ポリフェニレンエーテルエーテルケトン組成物の好ましい製造方法として、少なくともジハロゲン化芳香族ケトン化合物、ジヒドロキシ芳香族化合物、塩基(A)、および有機極性溶媒を含む混合物(ア)を加熱して反応させる方法(a)、少なくとも線状ポリフェニレンエーテルエーテルケトン、ジハロゲン化芳香族ケトン化合物、ジヒドロキシ芳香族化合物、塩基(A)、および有機極性溶媒を含む混合物(イ)を加熱して反応させる方法(b)が例示できる。
環式ポリフェニレンエーテルエーテルケトン組成物の別の好ましい製造方法として、少なくとも線状ポリフェニレンエーテルエーテルケトン、塩基性化合物(B)、有機極性溶媒を含む混合物(ウ)を加熱して反応させることによる製造方法(c)を挙げることができる。
本発明の環式ポリフェニレンエーテルエーテルケトン組成物は、(8)項に記した製造方法により得られた反応混合物から分離回収することにより得ることが可能である。上記製造方法により得られた反応混合物には少なくとも環式ポリフェニレンエーテルエーテルケトン、線状ポリフェニレンエーテルエーテルケトン及び有機極性溶媒が含まれ、その他成分として未反応原料や副生塩、水、共沸溶媒などが含まれる場合もある。この様な反応混合物から環式ポリフェニレンエーテルエーテルケトンを回収する方法に特に制限はなく、例えば必要に応じて有機極性溶媒の一部もしくは大部分を蒸留などの操作により除去した後に、ポリフェニレンエーテルエーテルケトン成分に対する溶解性が低く且つ有機極性溶媒と混和し、副生塩に対して溶解性を有する溶剤と必要に応じて加熱下で接触させて、環式ポリフェニレンエーテルエーテルケトンを線状ポリフェニレンエーテルエーテルケトンとの混合固体として回収する方法が例示できる。このような特性を有する溶剤は一般に比較的極性の高い溶剤であり、用いた有機極性溶媒や副生塩の種類により好ましい溶剤は異なるので限定はできないが、例えば水やメタノール、エタノール、プロパノール、イソプロパノール、ブタノール、ヘキサノールに代表されるアルコール類、アセトン、メチルエチルケトンに代表されるケトン類、酢酸エチル、酢酸ブチルなどに代表される酢酸エステル類が例示でき、入手性、経済性の観点から水、メタノール及びアセトンが好ましく、水が特に好ましい。
本発明の環式ポリフェニレンエーテルエーテルケトン組成物はポリフェニレンエーテルエーテルケトンプレポリマーとして用いて、加熱開環重合することによりポリフェニレンエーテルエーテルケトンへと転化することができる。なお、ここでのポリフェニレンエーテルエーテルケトンとは、パラフェニレンケトン、およびパラフェニレンエーテルを繰り返し構造単位に持つ、前記一般式(II)で表される線状化合物である。また、本発明の環式ポリフェニレンエーテルエーテルケトン組成物を加熱開環重合することにより得られるポリフェニレンエーテルエーテルケトンの還元粘度(η)に特に制限はないが、好ましい範囲として0.1~2.5dL/g、より好ましくは0.2~2.0dL/g、さらに好ましくは0.3~1.8dL/gを例示できる。
また、加熱方法としては、通常の重合反応装置を用いる方法で行うのはもちろんのこと、成形品を製造する型内で行っても良いし、押出機や溶融混練機を用いて行うなど、加熱機構を具備した装置であれば特に制限なく行うことが可能であり、バッチ式、連続式など公知の方法が採用できる。
本発明の環式ポリフェニレンエーテルエーテルケトン組成物は、熱可塑性樹脂に配合することにより、熱可塑性樹脂の溶融粘度を大幅に低減させる傾向が強く、熱可塑性樹脂の流動性向上の効果を発現する。これは、環式ポリフェニレンエーテルエーテルケトンが、通常の線状化合物や線状ポリマーと異なり末端構造を持たないため、分子間の絡み合いが小さくなることに起因する効果である。
