− 0.900g/cm3未満の密度を有し(ASTM D792により決定)、ポリマー(A)の重量基準で0.05〜15重量%の、6個以上の炭素原子数を有する少なくとも1種の長鎖α−オレフィンとの少なくとも1種のエチレンコポリマー[ポリマー(O)];
を含む、フルオロポリマー組成物[組成物(C)]である。
(a)繰り返し単位の合計量に対して30〜45モル%、好ましくは35〜43モル%の範囲の量でのエチレン(E)由来の繰り返し単位;
(b)繰り返し単位の合計量に対して55〜70モル%、好ましくは57〜65モル%の範囲の量でのクロロトリフルオロエチレン(CTFE)、テトラフルオロエチレン(TFE)、又はこれらの混合物のうちの少なくとも1種由来の繰り返し単位;を含み、
(c)繰り返し単位の合計量に対して0〜3モル%、好ましくは0〜2モル%の繰り返し単位(b)は、1種以上のフッ素化及び/又は水素化コモノマー(類)由来の繰り返し単位によって置き換えられていてもよい。
(a)40〜43モル%の量の、エチレン(E)由来の繰り返し単位と;
(b)繰り返し単位の合計量に対して57〜60モル%の量のクロロトリフルオロエチレン(CTFE)由来の繰り返し単位と;
から本質的になるものである。
ポリマー
ポリマー(A−1):は、180℃の融点(Tm2)、約18J/gの融解熱(ΔH2f)、及び1.4g/10分(230℃/2.16kg)のMFIを有する、41/59モル%のE/CTFEコポリマーである。
11個の温度ゾーンを備えた二軸押出機を使用する押出により、ペレットの形態のポリマー(A−1)と、ペレットの形態のポリマー(O−1)とを溶融相で混合することで本発明の組成物(1)のペレット(ポリマー(O−1)含有率:10重量%)又は比較の組成物(3c)のペレット(ポリマー(O−1)含有率:20重量%)を得ることにより、これらを含有する組成物を製造した。処理設定温度は以下の表1のとおりに定めた。
組成物1及び2cのそれぞれから作られる成形試験版を、次の条件で圧縮成形することにより得た。
温度:実施例1の組成物については230℃、実施例2cの素組成物については275℃;
時間:5’+1’+1’(予熱、脱気、成形);
圧力:16.000kg/h
冷却:16.000Kgでの冷水プレートプレスで急冷;
基材:KAPTON(登録商標)ポリイミドフィルム
上で詳述したとおりに得た成形試験板に対して、ASTM D638(タイプV)に従って23℃で機械試験を行った。下の表3に記載の結果は、本発明の組成物(1)から得られた成形物品が、有利なことには比較の組成物(2c)から得られた成形物品と比較して、低い引張弾性率及び大きい破断伸びを示すことを示している。
