Abstract:
(EN) Provided are a fluorine-containing elastic copolymer in which the contained amounts of metal elements and chloride ions are low, and a fluorine-containing elastic copolymer production method capable of obtaining a fluorine-containing elastic copolymer in which the contained amounts of metal elements and chloride ion contents are low. This fluorine-containing elastic copolymer has a metal element content of 20.0 ppm by mass or less and a chloride ion content of 1 ppm by mass or less. This production method for a fluorine-containing elastic copolymer comprises: causing a fluorine-containing elastic copolymer in a latex containing the fluorine-containing elastic copolymer to aggregate using an acid not including a metal element or a chloride ion; and washing the aggregated fluorine-containing elastic copolymer with a liquid medium having a metal element content of 2.0 ppm by mass or less and a chloride ion content of 2 ppm by mass or less.
(FR) L'invention concerne un copolymère élastique contenant du fluor dans lequel les quantités contenues d'éléments métalliques et d'ions chlorure sont faibles, et un procédé de production de copolymère élastique contenant du fluor capable d'obtenir un copolymère élastique contenant du fluor dans lequel les quantités contenues d'éléments métalliques et les teneurs en ions chlorure sont faibles. Le copolymère élastique contenant du fluor selon l'invention présente une teneur en élément métallique de 20,0 ppm en masse ou moins et une teneur en ions chlorure de 1 ppm en masse ou moins. Le procédé de production d'un copolymère élastique contenant du fluor selon l'invention consiste à : amener un copolymère élastique contenant du fluor dans un latex contenant le copolymère élastique contenant du fluor à s'agréger en utilisant un acide ne contenant pas d'élément métallique ou d'ion chlorure ; et laver le copolymère élastique contenant du fluor agrégé avec un milieu liquide ayant une teneur en éléments métalliques de 2,0 ppm en masse ou moins et une teneur en ions chlorure de 2 ppm en masse ou moins.
(JA) 金属元素および塩化物イオンの含有量が少ない含フッ素弾性共重合体、ならびに金属元素および塩化物イオンの含有量が少ない含フッ素弾性共重合体を得ることができる含フッ素弾性共重合体の製造方法の提供。 金属元素の含有量が20.0質量ppm以下であり、かつ塩化物イオンの含有量が1質量ppm以下である含フッ素弾性共重合体;含フッ素弾性共重合体を含むラテックス中の含フッ素弾性共重合体を、金属元素および塩化物イオンを有しない酸を用いて凝集させ、凝集した含フッ素弾性共重合体を、金属元素の含有量が2.0質量ppm以下であり、かつ塩化物イオンの含有量が2質量ppm以下である液状媒体で洗浄する含フッ素弾性共重合体の製造方法。
