摘要： A process for preparing particles of polyphenylene sulfide polymer (PPS), based on the use of a polyester polymer (PE) comprising units from a dicarboxylic acid component and a diol component, wherein at least 2 mol. % of the diol component is a poly(alkylene glycol). The process comprises the melt-blending of the PPS with the PE, the cooling the blend and the recovery of the particles by dissolution of the PE into water. The present invention relates to PPS particles obtained therefrom and to the use of these particles in SLS 3D printing, coatings and toughening of thermoset resins.

摘要： Composite particles contained in an ink are particles of a composite of a polyester resin including a sulfonic acid group and a basic dye. The polyester resin has a glass transition point of 40° C. to 70° C. The polyester resin includes a first repeating unit derived from a polyvalent carboxylic acid having the sulfonic acid group, a second repeating unit derived from a polyvalent carboxylic acid having no sulfonic acid group, and a third repeating unit derived from a polyhydric alcohol. The content ratio of the first repeating unit relative to the total amount of the first repeating unit and the second repeating unit is at least 1.5 mol % and no greater than 20.0 mol %. The mass ratio of the polyester resin to the basic dye is at least 1.0 and no greater than 10.0.
