<P>PROBLEM TO BE SOLVED: To provide a method for producing an aqueous dispersion of PPS resin micro particles, industrially useful with the use of a polymer surfactant having the weight average molecular weight of at least 2,000 by using the amount less than 10 mass parts, based on 100 pts.mass of PPS resin micro particles. <P>SOLUTION: The method for producing a stable aqueous dispersion of PPS resin micro particles of the average particle diameter of at most 1 μm includes mechanically dispersing resin micro particles of polyphenylene sulfide with the use of the polymer surfactant having the weight average molecular weight of at least 2,000 by using the amount less than 10 mass parts, based on 100 pts.mass of PPS resin micro particles. <P>COPYRIGHT: (C)2012,JPO&INPIT |
