Title:
POLYMER PARTICLE AND APPLICATION THEREOF
Document Type and Number:
Japanese Patent JP2020128536
Kind Code:
A
Abstract:
To provide polymer particles excellent in uniform dispersibility; and to provide an application thereof.SOLUTION: In a polymer particle, which is a polymer particle containing a surfactant, a variation coefficient of a volume-based particle size distribution is 13.0% or more and 25.0% or less, and 15.0 g water is added to 5.0 g polymer particles, and a dispersion treatment is performed as long as 60 minutes by using an ultrasonic cleaner, to thereby disperse the polymer particles into water, and then the solution is put into a centrifuge tube having an inner diameter of 24 mm, and subjected to centrifugal separation under a condition of K factor 6943 and a rotation time of 30 minutes by using a centrifugal separator, and thereafter supernatant liquid is recovered, and a concentration of a nonvolatile component in the supernatant liquid is less than 3.5 wt%.SELECTED DRAWING: None
