ABSTRACT OF THE DISCLOSURE Amine curable polymers are cured effectively by using a dispersion of complexes of 4,4'-methylene dianiline and/or racemic 2,3-di (4-aminophenyl) butane and selected alkali metal salts including sodium chloride. The particle size within the dispersion is such that at least about 90% of the particles have a diameter of no more than about 60 microns and preferably no more than about 30. The vehicle for the dispersion is an inert organic liquid preferably, di(2-ethylhexyl)phthalate.
