内容積18Lのオートクレーブに、ナフタレン-2,6-ジカルボン酸ジメチル2.20kg、2-プロパノール11.0kg、5%パラジウムを活性炭に担持させた触媒350g(50wt%含水品)を仕込んだ。次いで、オートクレーブ内の空気を窒素と置換し、さらに窒素を水素と置換した後、オートクレーブ内の圧力が0.8MPaとなるまで水素を供給した。次に、撹拌機を起動し、回転速度を500rpmに調整し、30分間かけて内温を100℃まで上げた後、さらに水素を供給し圧力を1MPaとした。その後、反応の進行による圧力低下に応じ、1MPaを維持するよう水素の供給を続けた。7時間後に圧力低下が無くなったので、オートクレーブを冷却し、未反応の残存水素を放出した後、オートクレーブから反応液を取り出した。反応液を濾過し、触媒を除去した後、分離濾液から2-プロパノールをエバポレーターで蒸発させた。得られた粗生成物に、2-プロパノールを4.40kg加え、再結晶により精製し、テトラリン-2,6-ジカルボン酸ジメチルを80%の収率で得た。尚、NMRの分析結果は下記の通りである。
1H‐NMR(400MHz CDCl3)δ7.76-7.96(2H m)、7.15(1H d)、3.89(3H s)、3.70(3H s)、2.70-3.09(5H m)、2.19-2.26(1H m)、1.80-1.95(1H m)
充填塔式精留塔、分縮器、全縮器、コールドトラップ、撹拌機、加熱装置及び窒素導入管を備えたポリエステル樹脂製造装置に、上述より得られたテトラリン-2,6-ジカルボン酸ジメチル543g、エチレングリコール217g、テトラブチルチタネート0.171gを仕込み、窒素雰囲気で230℃まで昇温してエステル交換反応を行った。ジカルボン酸成分の反応転化率を85%以上とした後、テトラブチルチタネート0.171gを添加し、昇温と減圧を徐々に行い、245℃、133Pa以下で重縮合を行い、ポリエステル化合物(1)を得た。
下記の条件により、層Bを構成する材料を射出シリンダーから射出し、次いで層Aを構成する材料を別の射出シリンダーから、層Bを構成する材料と同時に射出し、次に層Aを構成する材料を必要量射出して射出金型内キャビティーを満たすことにより、B/A/Bの3層構成の射出成形体を得た後、射出成形体を所定の温度まで冷却し、ブロー金型へ移行した後にブロー成形を行うことでバイアル(ボトル部)を製造した。バイアルの総質量を24gとし、層Aの質量をバイアルの総質量の30質量%とした。層Bを構成する材料としてはシクロオレフィンポリマー(COP、日本ゼオン株式会社製、商品名:ZEONEX(登録商標)5000;ガラス転移温度69℃)を使用した。
全長89mm、外径40mmφ、肉厚1.8mmとした。尚、バイアルの製造には、射出ブロー一体型成形機(UNILOY製、型式:IBS 85、4個取り)を使用した。
(バイアルの成形条件)

23℃、成形体外部の相対湿度50%、内部の相対湿度100%の雰囲気にて、測定開始から30日目の酸素透過率を測定した。測定は、酸素透過率測定装置(MOCON社製、商品名:OX-TRAN 2-21 ML)を使用した。測定値が低いほど酸素バリア性が良好であることを示す。尚測定の検出下限界は酸素透過率5×10-5mL/(0.21atm・day・package)である。
上述のポリエステル化合物(1)100質量部に対し、ステアリン酸コバルト(II)をコバルト量が0.00025質量部となるようドライブレンドし、直径37mmのスクリューを2本有する2軸押出機に30kg/hの速度で前記材料を供給し、シリンダー温度220℃の条件にて溶融混練を行い、押出機ヘッドからストランドを押し出し、冷却後、ペレタイジングし、酸素吸収性樹脂組成物を得た。層Aを構成する材料として前記酸素吸収樹脂組成物を用い、上述した方法により酸素吸収性多層バイアルを製造した。次に、得られた酸素吸収性多層バイアルに、Co60線源より放出されるガンマ線を室温・空気中で50kGy照射した。次いで、ガンマ線照射したバイアルを定温乾燥器(ヤマト科学株式会社製、型式:DS400)に入れて、空気中で55℃、96時間の加熱処理を行った。その後、室温まで冷却した後にバイアルのYIと酸素透過率とを測定した。また、ガンマ線照射・加熱処理の後のバイアルをアルミ箔積層フィルムからなるバリア袋に、空気量300ccとともにそれぞれ1本ずつ入れ、23℃/50%相対湿度(RH)で1日間保存し、密封袋内の臭気の有無を確認した。また、ガンマ線照射・加熱処理後に容器の変形の有無を目視で確認した。これらの結果を表1に示す。
