Abstract
Finely divided ethylene polymer particles having a smooth surface and regular spherical configuration are prepared by a method in which an ethylene polymer, an organic solvent for the polymer and water are charged into a vessel, the charge is stirred to mix the organic solvent, water and ethylene polymer, the charge is heated to a temperature at which the ethylene polymer is completely dissolved in the organic solvent, so as to form an organic solvent solution of the ethylene polymer mixed with water, the charge is cooled and, then, the mixture of organic solvent and water is evaporated away from the charge so as to allow the ethylene polymer to deposit in the form of finely divided particles from the charge.
