Abstract

1. Способ получения фторсодержащего полимера, включающий: ! (i) получение водной дисперсии фторполимерных частиц путем полимеризации одного или нескольких фторсодержащих олефинов и факультативно одного или нескольких фторсодержащих или не содержащих фтора сомономеров способом водоэмульсионной полимеризации, причем инициация полимеризации проводится в отсутствие фторированного поверхностно-активного вещества и никакие фторированные поверхностно-активные вещества не добавляются в процессе полимеризации; ! (ii) выделение фторсодержащего полимера из водной дисперсии с получением указанного фторсодержащего полимера и сточных вод; ! (iii) и соприкосновение указанных сточных вод с анионообменной смолой; или ! (iv) альтернативно этапам (ii) и (iii), соприкосновение указанной водной дисперсии с анионообменной смолой с последующим отделением указанной анионообменной смолы от указанной водной дисперсии. ! 2. Способ по п.1, отличающийся тем, что указанный фторсодержащий полимер представляет собой аморфный фторсодержащий полимер. ! 3. Способ по п.1, отличающийся тем, что частицы фторполимера имеют среднеобъемный диаметр 300 нм или более. ! 4. Способ по п.1, отличающийся тем, что фторсодержащий полимер имеет частично фторированную углеродную цепь. ! 5. Способ по п.1, отличающийся тем, что указанная водная дисперсия и указанные сточные воды практически не содержат неионных поверхностно-активных веществ. ! 6. Способ по п.1, отличающийся тем, что количество твердого вещества в указанной водной дисперсии составляет от 10 до 40% (в./в.).
