METHOD FOR PURIFYING MATERIAL TO BE TREATED AND METHOD FOR PRODUCING COAGULATED MATERIAL
摘要
<p>A method for purifying a material to be treated, characterized in that it comprises contacting a material to be treated containing a fluorine-containing surfactant with a substance [A], to thereby remove the fluorine-containing surfactant, wherein the substance [A] is a gas under standard conditions (10<5> Pa, 0°C); and a method for producing a coagulated material comprising a polymer from an aqueous dispersion. The method can be suitably employed for removing a fluorine-containing surfactant from a material to be treated containing the fluorine-containing surfactant.</p>
