Title (EN) METHOD FOR MANUFACTURING FLUORINE-CONTAINING POLYMER PARTICLES
(FR) PROCÉDÉ DE FABRICATION DE PARTICULES POLYMÈRES CONTENANT DU FLUOR
(JA) 含フッ素ポリマー粒子の製造方法
Abstract:
(EN) Provided is a method for manufacturing fluorine-containing polymer particles which restricts formation of minute particles. The for fluorine-containing polymer particles has (i) a step for preparing a solution or a dispersion by dissolving or dispersing a fluorine-containing polymer (A) in a solvent (B), the step satisfying the requirements that the solvent (B) contain a good solvent (B2) such that the degree of swelling of the fluorine-containing polymer (A) exceeds 50% and that the degree of swelling (SB) due to the solvent (B) be 50‑1200%, and (ii) a step for forming fluorine-containing polymer (A) particles by mixing the solution or the dispersion of the fluorine-containing polymer (A) with a solvent (C), the step satisfying the requirements that the solvent (C) contain a poor solvent (C1) such that the degree of swelling is 50% or less, that the degree of swelling (SBC) due to a mixed solvent (BC) comprising the solvent (B) and the solvent (C) be 0‑100%, that the ratio (WC/WB) between the mass (WC) of the solvent (C) and the mass (WB) of the solvent (B) be 1‑5, and that SBC/SB 0.5 or less.
(FR) Le procédé de fabrication de particules polymères contenant du fluor ci-décrit permet de limiter la formation de minuscules particules. Il consiste à (i) préparer une solution ou une dispersion en dissolvant ou en dispersant un polymère fluoré (A) dans un solvant (B), sous réserve que le solvant (B) contienne un bon solvant (B2) tel que le degré de gonflement du polymère fluoré (A) dépasse 50 % et le degré de gonflement (SB) dû au solvant (B) soit de 50-1200 %, et (ii) former des particules de polymère fluoré (A) en mélangeant la solution ou la dispersion du polymère (A) avec un solvant (C), sous réserve que le solvant (C) contienne un solvant médiocre (C1) tel que le degré de gonflement soit de 50 % ou moins, que le degré de gonflement (SBC) dû à un solvant mixte (BC) comprenant le solvant (B) et le solvant (C) soit de 0-100 %, que le rapport (WC/WB) entre la masse (WC) du solvant (C) et la masse (WB) du solvant (B) soit de 1-5, et que SBC/SB soit de 0,5 ou moins.
(JA)  微小な粒子の生成が抑えられた含フッ素ポリマー粒子の製造方法を提供する。  (i)含フッ素ポリマー(A)が溶媒(B)に溶解または分散した溶液または分散液を調製する工程であり、溶媒(B)が、含フッ素ポリマー(A)の膨潤度が50%超となる良溶媒(B2)を含む、溶媒(B)による膨潤度(S)が50~1200%である、の条件を満足する工程と;(ii)含フッ素ポリマー(A)の溶液または分散液と溶媒(C)とを混合して含フッ素ポリマー(A)粒子を形成する工程であり、溶媒(C)が、膨潤度が50%以下となる貧溶媒(C1)を含む、溶媒(B)と溶媒(C)との混合溶媒(BC)による膨潤度(SBC)が0~100%である、溶媒(C)の質量(W)と溶媒(B)の質量(W)との比(W/W)が1~5である、SBC/Sが0.5以下である、の条件を満足する工程とを有する含フッ素ポリマー粒子の製造方法。
