Description
mは0又は1であり、nは0又は1であり、n+m=1又は2、Xは、1〜12個の炭素原子を持ち、任意選択でヘテロ原子を含む、直鎖又は分岐鎖の、脂肪族又は芳香族炭化水素部分である。)のアジドと接触させる工程を含む、官能化エチレンベースの(コ)ポリマーを調製するための工程に関する。
上述の工程により官能化エチレンベースの(コ)ポリマーを調製する工程と、
官能化エチレンベースの(コ)ポリマーを有機過酸化物と接触させてポリマー/過酸化物混合物を生成する工程と、
上記ポリマー/過酸化物混合物を140〜300℃の範囲の温度で加熱する工程とを含むエチレンベースの(コ)ポリマーを改質するための工程に関する。
mは0又は1であり、nは0又は1であり、n+m=1又は2、好ましくは1、Xは、1〜12個の炭素原子を持ち、任意選択でヘテロ原子を含む、直鎖又は分岐鎖の、脂肪族又は芳香族炭化水素部分である。)を有する。
LDPE(BPD2000、旧Ineos)を、0、1又は2phr シトラコンベンゼンスルホニルアジドと共にThermo Scientific Haake PTW16、40L/Dラボ押出機で押出した。押出機の混合ゾーン内の温度は180〜230℃の範囲、スクリュー速度は150rpm、押出量は1kg/時間、押出機内での滞留時間は約90秒であった。これらの設定は、FT−IR分光法により確認された通り、アジドを完全に分解するのに十分であった。
エチレン−プロピレンコポリマー(EPM)(不飽和なし)を実施例1で用いたシトラコンアジドで改質した。この実現のために、カーボンブラック充填材及びオイルを含むEPMベースの化合物(組成については表2を参照。)を、ゴムの2%(phr)のシトラコンベンゼンスルホニルアジドと混合して、バンバリータイプの密閉式混練機で150〜180℃で熱処理し、アジドをEPMにグラフトさせた。
EPMを170℃で加熱することにより硬化した。
硬化速度及び架橋密度を、レオメトリー(Alfa technologies rheometer MDR 2000)を用いて評価した。結果を表2に示す。
