An object of the present invention is to provide polymer particles having excellent dispersion stability and uses thereof. SOLUTION: The polymer particles contain a surfactant, the coefficient of variation of the particle diameter is 15.0% or less, 15.0 g of water is added to 5.0 g of the polymer particles, and an ultrasonic cleaner is used. The polymer particles were dispersed in water by performing a dispersion treatment for 60 minutes using a centrifuge, and the mixture was placed in a centrifuge tube having an inner diameter of 24 mm, centrifuged using a centrifuge at a K factor of 6943, and a rotation time of 30 minutes. When the liquid is recovered, the concentration of the non-volatile components in the supernatant is less than 1.0% by weight. [Selection diagram] Fig. 1 |
