Abstract

PURPOSE: Fine particles usable for dry binders, readily soluble in organic solvents, prepared by finely dispersing a water-insoluble polyanion high polymer into particles of specific size or less.
CONSTITUTION: A water-insoluble polyanion high polymer, e.g. cellulose acetate phthalate, is dissolved in water containing a basic substance, e.g. NaOH, or the water-soluble base salt of the high polymer is dissolved in water. An acidic substance, e.g. hydrochloric acid, capable of neutralizing the above substance is added to the solution with agitation, if necessary under heating, to form a hydrosol or gel (H) of the polymer, which is heated to a temperature above the dehydration and solidification point of H with agitation. Preferably, a surfactant or warer-soluble high polymer may be present in neutralization. The particle size is 10μ or less, or 1μ or less with vigorous agitation.
USE: Dry tableting binders.
