Description
1)−R1C5F10CH2C4F 9 により示され、多孔質膜がPTFE延伸多孔質膜である、撥油性が付与された通気フィルタ、を提供する。ここで、R1 は、炭素数が1〜12のアルキレン基またはフェニレン基である。
1)−R1C5F10CH2C4F 9 を有する撥油剤が使用される。ここで、R1 は、炭素数が1〜12、好ましくは1〜10のアルキレン基、あるいはフェニレン基である。上記1)で示されるフッ素含有炭化水素基は、R 1 がアルキレン基であるときには、直鎖状フルオロアルキル基となる。なお、上記の「直鎖状」とは、フッ素含有炭化水素基の炭素骨格が分岐した2以上の末端を有さないことを明確にする趣旨であって、R 1 としてフェニレン基を含むことを除外する意味ではない。
a)CH2=CR3COOR1C5F10CH2C4F 9 により示される化合物を単量体の少なくとも一部とする重合体を挙げることができる。ここで、R 1 は上述のとおりである。また、R 3 は、水素原子またはメチル基である。
