A new composition is described comprising a synthetic, artificial or natu polymer and a flameproofing additive imparting self-extinguishing properties to the composition and to the articles, such as moulded, spun or woven articles, made therefrom, said additive being the product of the reaction of melamine with acidic compounds, such as organic acids or anhydrides and inorganic acids. The process for making said additive by said reaction, preferably in the presence of water, is also described. The said composition may be made by introducing said additive in any manufacturing stage, viz. to the monomers (if the polymer is a synthetic one), to the molten polymer, to polymer solutions such as viscose dope, to polymer chips during extrusion, or to finished products e.g. by applying a finish to fabrics.
