Abstract

Preparing a dispersion of methylenedianiline/inorganic salt complex curing agent of small particle size which comprises: (a) agitating while reacting 3 moles of 4,4'-methylenedianiline with not less than 1 mole of a salt selected from the group consisting of sodium chloride, sodium bromide, sodium iodide, lithium chloride, lithium bromide and lithium iodide in the presence of water and a benzenoid hydrocarbon solvent for the methylenedianiline; (b) separating the resulting complex having an average particle size diameter of less than about 10 μm from the bulk of the hydrocarbon solvent; (c) drying said complex; and (d) dispersing said complex in a substantially nonvolatile liquid carrier that is inert to the complex; with the proviso that steps (c) and (d) can be carried out in any order or substantially simultaneously.
