Description
Tg値:>180℃
条件化HDT/B:>140℃
相対粘度:>1.45
を有する。
押出物は成形体、チューブ、ホース、フィルム、プレートまたは中空体などと考えられる。
チャンバー容積26リットルを有するTuttnauerからの2549E圧力オートクレーブを用いる。4つのレベルのサンプルを受けるための穴の開いたシートを有するシーブ(篩)を水平方向に伸びた圧力チャンバーの円筒内部に置く。
ISOテスト物体(標準:ISO/CD3167、A1型、170×20/10×4mm)を前処理せずに、互いに触れないように射出成形物としてシーブ上に並べる。オートクレーブを閉じて密閉する。要求されるテスト物体の量を所定の除去時間に応じて確立する。
オートクレーブを134℃に加熱し、予め配分した水(約350ml)をオートクレーブ中で蒸気化する。この工程は2バールまで昇る蒸気圧で20〜30分続く。5×7分後(連続5回サイクルに匹敵)、オートクレーブを室温に冷却する。次の5つのブロックを開始する。3つのテスト物体を所望の除去時間に従って各々の時間で取除く。
ISO527に従う破断テストをさらに処理をせず室温に冷却した3つの物体について行う。5mm/分のトラクションスピードを2%ストレッチングまで用い、50mm/分のトラクションスピードを2%越えのストレッチングに用いる。機械的な値は各々の3つの値からの平均値を表わす。
テスト物体をX回の熱蒸気殺菌サイクル後に残る破断伸びが降伏点での伸びを超える限り、構造に関して熱蒸気殺菌性と考える。透明性は第2の基準として確立する。熱蒸気殺菌性はクラックが発生せず、裸眼での観察により退色が無い場合および少なくとも70%の光透過性(本発明に用いられる定義によれば)が提供されるならば透明性に関して提供する。
融点25〜45℃、好ましくは33.5〜44℃を有するモノマーをビス−(4−アミノ−シクロヘキシル)メタン(PACM)として用いてもよい。
脱イオン水42mgを300リットル圧力オートクレーブの分配容器に入れ、IPS17.0kgおよびTPS17.0kgの混合物を攪拌しながら投入する。攪拌を止めてMACM48.2kg、ラクタム12に28.8kgおよび安息香酸0.54kgを加える。
攪拌下バッチを295℃に加熱し、20バールで4時間圧力相中に保持する。1.5時間内に、大気圧にし、次いで40分間脱気する。
ポリマー溶融物を取り出し、水浴中(65℃)で冷却し、粒状化する。粒状物を窒素雰囲気下100℃で24時間乾燥し、水含量0.06重量%以下にする。
DA: ジアミン
DDS: ドデカン二酸
HDT: 熱歪温度
IPS: イソフタル酸(I)
ラクタム12:ラウリンラクタム(L)
MACM: ビス−(4−アミノ−3−メチル−シクロヘキシル)メタン
PACM: ビス−(4−アミノ−シクロヘキシル)メタン
Tg: ガラス転移温度
TPS: テレフタル酸(T)
RV: 相対粘度
本発明による組成物の高い相対粘度の場合において、より高い数の熱蒸気殺菌サイクルの後でも要求が満たされていることがわかる。
/(y1+y2)>0.5に固定されている。即ち、y1がy2よりも常に大きい。また、y2は0であってもよく、y1は0の可能性はない。公報の第2頁第24〜25行にはまた、TPSおよびIPSの混合物の場合、TPS成分がIPS成分よりも多く用いられると記載されている。EP 0 313 436 A1に記載されたコポリアミドはラクタムおよびジアミン含有量に関して、本発明のコポリアミドと少しだけ重複する。TPSはEP 0 313 436 A1中でIPS/TPSの比より優先しなければならず、逆にIPSは本発明によればコポリアミド中で優先されなければならない。また、TPS成分は本発明によればコポリアミド中において0でもあってもよく、TPSはEP 0 313 436 A1においては絶対的に要求される。さらに、EP 0 313 436 A1中の必要により高いラクタム12成分は本発明では重要である。
