Description
これらの実施例は、重合開始時の反応混合物中の全2,6−ジメチルフェノールの比率、該反応混合物に残りの2,6−ジメチルフェノールを添加する時間、該反応混合物中の2,6−ジメチルフェノールと触媒金属とのモル比、該反応混合物に供給した酸素と2,6−ジメチルフェノールとのモル比、形成段階と排出段階における該反応混合物の温度、全反応時間、重合反応終了から沈殿開始までの時間、および該重合反応の終了から沈殿完了までの時間、を含むポリ(2,6−ジメチル−1,4−フェニレンエーテル)プロセス変数における変化を示す。
これらの実験は実験室規模で行ったものであり、個々のプロセス変数による効果を見ようとするものである。すべての反応混合物には、2,6−ジメチルフェノール270gとトルエン3,200gが含まれている。2,6−ジメチルフェノールの添加時間は常に45分間とした。該反応における形成段階の間、酸素濃度を10体積%に維持した。130分反応させた後(形成段階終了時)、反応槽への酸素流入を停止した。その後、反応混合物の温度を60℃に上げて、ニトリロ三酢酸三ナトリウム溶液を添加して銅触媒をキレート化した。60℃で90分間攪拌した後、該混合物を70℃で50分間遠心分離して前記水相と有機相とを分離した。有機相をメタノール反溶媒と結合させて該ポリ(2,6−ジメチル−1,4−フェニレンエーテル)を沈殿させ、生成したポリ(2,6−ジメチル−1,4−フェニレンエーテル)粉末をろ過し、135℃で一晩乾燥させた。
これらの比較実施例は、キレート化温度および時間がポリ(2,6−ジメチル−1,4−フェニレンエーテル)の固有粘度に与える影響を示している。17.3gの触媒と、5.33gのジ−t−ブチルエチレンジアミンと、9.86gのジ−n−ブチルアミン、32.1gのジメチル−n−ブチルアミンと、全2,6−ジメチルフェノールの内、最初の5質量%のポリ(2,6−ジメチル−1,4−フェニレンエーテル)と、を用い、酸素流入速度0.30標準L/分、発熱段階温度30℃にて、ポリ(2,6−ジメチル−1,4−フェニレンエーテル)を実験室規模で製造した。酸素供給を停止後、生成した溶液を2つのジャケット付き容器に分け、ニトリロ三酢酸三ナトリウムと水を添加した。一つの容器を50℃に、他方を60℃に維持した。記録した時間に容器から試料を採取し、(トルエンで希釈後)ゲルパーミエーションクロマトグラフィに注入して、ポリ(2,6−ジメチル−1,4−フェニレンエーテル)の固有粘度を求めた。表3に示した結果から、ポリ(2,6−ジメチル−1,4−フェニレンエーテル)の固有粘度は、キレート化温度が50℃の場合は約5%の割合で低下し、キレート化温度が60℃の場合には約11%の割合で低下することがわかる。
