Abstract

PURPOSE: To prepare extremely uniform, porous particles having proper size, with a relatively simple apparatus, continuously, by contacting a suspension of thermoplastic polymer fine powder with steam under specific conditions.
CONSTITUTION: A suspension of fine powder of a thermoplastic polymer, e.g. ABS resin, is fed to the pipe 3 from the tank A with the pump B, and at the same time, hot steam is supplied to the pipe through the valve 2 to keep the temperature of the mixing system above the heat-distortion temperature of the polymer. The polymer suspension is made to contact with the hot steam continuously for ≥0.05sec keeping the volume ratio of gas/(liquid + solid) to 0.5W100, pref. 4W30. After the treatment, cooling medium D (e.g. water) is injected into said mixing system to condense the steam and the condensed water is discharged through the valve 6 from the system.
