Abstract
Spherical resin particles in micron order with a narrow particle diameter distribution, methods for the production thereof and uses thereof are disclosed. Overcoming various problems comprised in the hitherto-known polymerization granulation methods, resin particles using a condensation polymer in micron order of the present invention having spherical form and narrow particle diameter distribution serve well for various applications.
