Abstract
The present invention relates to a method for preparing spherical cured polymer particles from a curable composition. The method comprises the steps of: dropping a curable composition onto a substrate having a water contact angle of 150° to 170° at 25° C. to form droplets of the curable composition; and curing the droplets to form the polymer particles.
