Abstract
Description
1) ヘキセン-1コモノマー単位の含有量が2~4重量%、好ましくは2~3.5重量%、特に2.2~4重量%または2.2~3.5重量%であること
2) 溶融温度TmIが115℃以上、好ましくは117℃以上であること
-X線結晶化度が48%~53%であること
-0℃でキシレンに可溶な画分の含有量が8重量%以下、より好ましくは6重量%以下であり、全ての場合、下限が3.2重量%であり、前記量はコポリマーの総重量に対するものである。
-成形30日後に圧縮プラークに対して標準ISO 178:2019に準拠して測定された曲げ弾性率が、200~300MPa、より好ましくは220~280MPaであること
-成形30日後にISO 8986-2:20 09に準拠した圧縮プラークに対してISO 180:2000に準拠して測定された23℃でのアイゾット耐衝撃性が30~65kJ/m2、特に35~60kJ/m2であること
-成形30日後にISO 8986-2:20 09に準拠した圧縮プラークに対してISO 180:2000に準拠して測定された0℃でのアイゾット耐衝撃性が20~50kJ/m2、特に20~45kJ/m2であること
-成形30日後に圧縮プラークに対してISO 527-1:2019に準拠して測定された破断伸びが250%~350%であること
HH=A/Σ
BH=B/Σ
BB=C/Σ
ただし(Σ=A+B+C
[H]=(HH+0.5 HB)*100
[B]=(BB+0.5 HB)*100
次に、全スペクトルに沿って、2相モデルに従ってアモルファス領域と結晶領域を分離する適切なアモルファスプロファイルを定義する。したがって、カウント/秒・2Θで表される非晶質領域(Aa)を、非晶質プロファイルとベースラインとの間の領域、およびカウント/秒・2Θで表される結晶領域(Ca)をCa=Ta-Aaとして計算してもよい。
成形30日後にISO 8986-2:20 09に準拠して、ISO 180:2000に準拠した圧縮プラークに対して測定して決定した。
P.I:= 54.6x(弾性率分離)-1.76
弾性率分離は次のように定義される。
弾性率分離=G’での周波数=500Pa/G’’での周波数=500Pa
ここで、G’は貯蔵弾性率であり、G’は損失弾性率である。
