Abstract
Organopolysiloxane powder is prepared from an organopolysiloxane solution by admitting the organopolysiloxane solution into a planetary-screw mixer and agitating the solution at a sufficient temperature to allow a low-boiling liquid component to evaporate from the solution, thereby separating the low-boiling liquid component from the solution.
