ABSTRACT:
A multi-cellular cellulose particle having a multiplicity of cells spaced from one another by cell membranes is described, which cells have a maximum inscribed sphere diameter of larger than 2 .mu.m. The cells have a continuous hole structure in which the cells communicate with one another through openings in the membranes separating two adjacent cells. The multi-cellular cellulose particle is prepared by forming drops of a solution of cellulose or a cellulose derivative, cooling the drops at a temperature lower than the solidification temperature of the solution to freeze the drops, and removing the solvent by extraction or nullifying the dissolving power of the solvent.
