摘要: Amorphous perfluorinated copolymers, comprising cyclic perfluorinated units deriving from at least two different perfluorinated comonomers, optionally with units deriving from a perfluorinated monomer containing at least one olefinic unsaturation (perfluoroolefin), or comprising cyclic perfluorinated units and units deriving from a perfluorinated monomer containing at least one olefinic unsaturation, said perfluorinated copolymers having the following combination of properties:
substantial absence of unstable polar end groups,
polymer Tg higher than 120°C,
narrow monomeric composition distribution.摘要翻译: 无定形全氟化共聚物,包括衍生自至少两种不同全氟化共聚单体的环状全氟化单元,任选地衍生自含有至少一种烯属不饱和(全氟烯烃)的全氟化单体的单元,或包含环状全氟化单元和衍生自至少含有全氟化单体的单元 所述全氟化共聚物具有以下性质的组合:基本上不存在不稳定的极性端基,高于120℃的聚合物Tg,窄的单体组成分布。
