Abstract
(EN) The present invention addresses the problem of providing a novel method capable of efficiently purifying polymer fine particles from a latex at a reduced environmental burden. Provided is a method for producing purified polymer fine particles (A) that includes an organic solvent mixing step for mixing a latex containing polymer fine particles (A) and an emulsifier having a polyethylene group with an organic solvent (B) and a mixed state maintenance step for stirring and/or allowing to stand the mixture obtained in the organic solvent mixing step.
(FR) La présente invention a pour objet un nouveau procédé permettant de purifier efficacement des fines particules de polymère à partir d'un latex avec une charge environnementale réduite. À cet effet, l'invention porte sur un procédé pour la production de fines particules de polymère (A) purifiées, qui comprend une étape de mélange avec un solvant organique consistant à mélanger avec un solvant organique (B) un latex contenant de fines particules de polymère (A) et un émulsifiant ayant un groupe polyéthylène et une étape de maintien d'état mélangé consistant à agiter et/ou laisser reposer le mélange obtenu à l'étape de mélange avec un solvant organique.
(JA) ラテックスから重合体微粒子を効率的に精製し得る、環境負荷が低減された新規の方法を提供することを課題とする。重合体微粒子（Ａ）およびポリエチレン基を有する乳化剤を含有するラテックスと、有機溶媒（Ｂ）とを混合する有機溶媒混合工程、並びに前記有機溶媒混合工程で得られる混合物を静置および／または撹拌する混合状態維持工程、を含む、精製重合体微粒子（Ａ）の製造方法を提供する。
