| description | PROBLEM TO BE SOLVED: To provide a multilayer syringe barrel for prefilled syringes that has excellent oxygen barrier properties after stored for a fixed period in a state of being filled with a chemical solution and has suppressed whitening, and a syringe and a prefilled syringe.SOLUTION: A multilayer syringe barrel for prefilled syringes has a layer (X) containing a cyclo olefinic polymer with a glass transition temperature of 100°C or less as the main component, and a layer (Y) containing a polyamide resin (A) as the main component, where the polyamide resin (A) has a diamine-derived constitutional unit and a dicarboxylate-derived constitutional unit, where 70 mol% or more of the diamine-derived constitutional unit is derived from m-xylylenediamine, and 30-60 mol% of the dicarboxylate-derived constitutional unit is derived from C4-20 α,ω-linear aliphatic dicarboxylate and 70-40 mol% of it is derived from isophthalic acid.SELECTED DRAWING: Figure 1
【課題】 薬液を充填した状態で一定期間保存した後の、酸素バリア性に優れ、かつ、白化が抑制されたプレフィルドシリンジ用多層シリンジバレル、ならびに、シリンジおよびプレフィルドシリンジの提供。【解決手段】 ガラス転移温度が１００℃より低いシクロオレフィン系ポリマーを主成分とする層（Ｘ）およびポリアミド樹脂（Ａ）を主成分とする層（Ｙ）を有し、前記ポリアミド樹脂（Ａ）が、ジアミン由来の構成単位と、ジカルボン酸由来の構成単位から構成され、前記ジアミン由来の構成単位の７０モル％以上がメタキシリレンジアミンに由来し、前記ジカルボン酸由来の構成単位の３０〜６０モル％が炭素数４〜２０のα，ω−直鎖脂肪族ジカルボン酸に由来し、７０〜４０モル％がイソフタル酸に由来するプレフィルドシリンジ用多層シリンジバレル。【選択図】図１ |
