Abstract

PURPOSE: To prepare the titled particles suitable for a gel filtration material, in high reproducibility, by dissolving a cellulose triacetate derived from crystalline cellulose having a specific polymerization degree in a chlorinated hydrocarbon solvent, dispersing the solution in an aqueous medium, evaporating the solvent, and saponifying the cellulose ester.
CONSTITUTION: (A) A cellulose triacetate derived from cryatalline cellulose having a specific polymerization degree or its mixture with a cellulose triacetate derived from cellulose having crystalline regions and amorphous regions, is dissolved in (B) a mixed solvent composed of (a) a chlorinated hydrocarbon having a boiling point of lower than that of the aqueous medium and (b) pref. ≥6C aliphatic higher alcohol. The solution thus obtained is dispersed in an aqueous medium, and the chlorinated hydrocarbon is evaporated and removed from the resulting droplets. The spherical particles thus obtained are saponified to obtain the objective particles.
EFFECT: The cellulose density and the threshold molecular weight can be adjusted over wide ranges.
