Description
本発明では、熱可塑性樹脂(C)として、メタキシリレンジアミンを70モル%以上(100モル%を含む)含むジアミン成分と、炭素数4〜20のα,ω−直鎖脂肪族ジカルボン酸を50モル%以上(100モル%を含む)含むジカルボン酸成分とを重縮合して得られるポリアミドオリゴマーまたは低分子量ポリアミドを使用することができる。
面積(平均値)<0.054μm2 (1)
長軸(平均値)<0.6μm (2)
短軸(平均値)<0.09μm (3)
ここで、面積、長軸および短軸は、多層ボトルを立て、水平方向にカットして得た0.1μm厚み程度の超薄切片の断面を、多層ボトルを立てた際の垂直方向から顕微鏡観察することで測定できる。本発明の多層ボトルでは、通常、バリア層中の熱可塑性樹脂(C)は延伸されて平板状になって分散しているため、上記垂直方向から観察すると条件(1)〜(3)を満たす形状を有する。前記面積は0.001〜0.054μm2未満であることがより好ましく、長軸は0.1〜0.6μm未満であることがより好ましく、短軸は0.01〜0.09μm未満であることがより好ましい。長軸/短軸は、1.1〜100が好ましく、2〜50がより好ましく、3〜10が特に好ましい。
熱可塑性樹脂(C)がバリア層中で上記の条件を満たすように分散している場合、ボトルに衝撃が加わったときのバリア層内部でのエネルギー緩和が容易となり、また、熱可塑性樹脂(C)がエネルギーを吸収し易くなることから、得られた多層ボトルは耐層間剥離性に優れたものとなる。
なお、多層プリフォームを製造する方法は、上記方法だけに限定されるものではない。
ASTM D2463−95 ProcedureBに基づいた容器の落下試験により求めた層間剥離高さ(cm)にて評価した。層間剥離高さが高いほど、耐層間剥離性が良好であることを示す。まず、多層ボトルに水を満たしキャップをした後、多層ボトルを底部が床に衝突するように垂直に落下させ、層間剥離の有無を目視で判定した。落下高さを15cm間隔で高くしながら落下試験を繰り返し、層間剥離が生じた最小の落下高さを層間剥離高さとした。テストボトル数は30本。
23℃、相対湿度50%の雰囲気下にてASTM D3985に準じて測定した。測定は、モダンコントロールズ社製、OX−TRAN 10/50Aを使用した。尚、バリア層のOTRは成形したボトルからバリア層のみを取り出し測定した。バリア層のみを取り出すのが困難なときは、ポリエステル(A)層とバリア層からなるボトル胴部をシート状に切断し、該シートのOTR測定値、顕微鏡などにより求めた各層の厚みの測定値、および別に求めたポリエステル(A)層のOTR値から、バリア層のみのOTR値を計算することができる。または、ボトルのOTR値、ボトルの表面積および各層厚みから、バリア層のみのOTRを計算することもできる。
ブロー成形して得た多層ボトルの胴部からバリア層のみを取り出し、エポキシ樹脂に包埋した。エポキシ樹脂が硬化した後、ウルトラミクロトーム(Boeckeler Instruments製CR−X Power Tome XL)にて、サンプルをボトルMD(縦)方向に垂直に切り出し、0.1μm厚み程度の観察用切片を得た。これを胴メッシュにすくい上げて、顕微鏡観察に供した。なお、作製した超薄切片は塩化ルテニウム蒸気にて染色し、染色の濃淡により、バリア層中の熱可塑性樹脂(C)の分散状態を観察した。電子顕微鏡観察は、日立製、表面観察用透過型電子顕微鏡S4800を使用し、加速電圧30kV、電流10mA、測定倍率25,000倍、測定モードTEMの測定条件で行った。
下記の条件により、ポリエステル(A)層/バリア層/ポリエステル(A)層からなる3層プリフォーム(27g)を射出成形し、冷却後、プリフォームを加熱し2軸延伸ブロー成形を行い、多層ボトルを得た。
