Title:
POLYMER PARTICLES AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/171669
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing polymer particles which disperse uniformly and stably in a resin composition and in a dry coating film thereof (which have excellent dispersibility and dispersion stability) and for which the required time to disperse uniformly and stably in the resin composition is short. Provided as a means of solving the problem are polymer particles in which: (a) a surfactant that exhibits a solubility parameter (SP value) of 9.0-12.0 and that has a polyoxyalkylene chain is contained in amount per unit surface area of the polymer particles of 1.0×10-3 to 6.0×10-3 g/m2; (b) a surfactant that exhibits a solubility parameter (SP value) of 9.0-12.0 and that does not have polyoxyalkylene chain is contained in an amount per unit surface area of the polymer particles of 5.0×10-5 to 13.0×10-5 g/m2; and (c) the surface residue amount of nonvolatile components per unit surface area of the polymer particles is not more than 2.0×10-3 g/m2.
