Abstract
【解決手段】メルトインデックスが1〜3dg/分で、エチレン含有量がRCPの重量の2〜3.5重量%であるチーグラー‐ナッタ触媒系を用いて製造されたプロピレンとエチレンとのランダム共重合体(RCP)を用い、プレフォームの射出温度が少なくとも210℃にする。
Description
下記文献ではISBMで二段階法で物品を製造している。
下記文献ではISBMで二段階法で物品を製造している。
下記文献にはメタロセン触媒を使用して作ったプロピレンのホモ−またはコポリマーをISBMで使用することが開示されている。
上記の樹脂では特性が理想的にバランスした物品を作ることはできない。
本発明の他の目的は、2軸延伸後に優れた光学特性を有する医薬用小びんを製造するための、射出−延伸−ブロー成形法用プレフォームでの低溶融流動性ポリプロピレン樹脂の使用方法を提供することにある。
本発明のさらに他の目的は、厚さ分布の良い医薬用小びんを製造することにある。
本発明のさらに他の目的は、積重ね特性に優れた医薬用小びんを製造することにある。
本発明のさらに他の目的は、特に低温での耐落下試験性に優れた医薬用小びんを製造することにある。
上記目的の少なくとも一つの少なくとも一部は本発明によって達成できる。
本発明はさらに、プレフォームの製造方法と、この方法で得られるプレフォームと、このプレフォームの医薬用小びんの製造での使用と、プレフォームから製造した医薬用小びんとに関するものである。
本発明で使用するポリプロピレン樹脂はチーグラー−ナッタ(ZN)触媒系で製造したものが好ましい。ZN触媒系では本来的に多分散性指数が広いポリマーが作られる。多分散性指数は数平均分子量Mnに対する重量平均分子量Mwの比Mw/Mnで定義される。分子量はゲル浸透クロマトグラフ(Gel Permeation Chromatography、GPC)で測定する。チーグラー−ナッタ触媒系では一般に多分散性指数が少なくとも6のポリマーが得られる。メタロセン触媒およびシングルサイト触媒はZN触媒でないということは明らかである。
メルトインデックスは3dg/分以下である。好ましい最低MI2は1.5dg/分で、好ましい最大MI2は2.5dg/分、好ましくは2dg/分である。
一般に、このタイプの低溶融流動性樹脂は射出−延伸−ブロー成形の用途では使用されない。従って、射出−延伸−ブロー成形条件をこの樹脂で実施するのに合わせる。
樹脂は5000ppm以下の核剤を含むことができる。核剤が存在する場合、その量は200〜2500ppmにするのが好ましい。
さらに、この分野で一般的に使用される他の添加剤、例えば抗酸化剤または静電気防止剤を加えられることもできる。
プレフォームに生じる応力が最終製品の透明性および衝撃特性に大きな影響を与える。
射出延伸ブロー成形は下記の工程から成る:
(1)多重キャビティー金型で射出成形してプレフォームを作る。
(2)必要に応じてプレフォームを再加熱する。
(3)必要に応じて加熱されたプレフォームを平衡化帯域を通してプレフォーム壁に熱を均一に分散させる。
(4)必要に応じてプレフォームをプレ−ブロー階段でブローする。
(5)中心ロッドでプレフォームを軸線方向に延伸する。
(6)プレフォームを高圧空気によって放射方向に延伸する。
上記方法では延伸階段がクリティカルな階段である。プレフォームを均一に加熱し、最適化されたプロセスでプレフォームを製造する必要がある。
