Abstract: Described herein is a preparation process of a flame retardant composition made from brominated bismuth and/or antimony compounds complexed with melamine, in which melamine, at least one between the bismuth carbonate and antimony sesquioxide, hydrobromic acid in aqueous solution are placed in contact with each other so as to trigger chemical reactions which lead to the formation of a complex of brominated bismuth or brominated antimony with melamine and melamine bromohydrate. The reagents are placed in contact in the presence of at least one reaction carrier defined by at least one compound chosen from the group consisting of melamine, melamine phosphate, melamine polyphosphate, ammonium phosphate, ammonium polyphosphate, triphenyl-phosphate, graphite, silica, lignin, coke and compounds containing triazine rings condensed or linked by —NH groups. The reaction carrier is not involved in the reactions. There are no polymeric compounds in quantities such as to create a polymer matrix. The reagents being introduced into the reactor in an amount defined by the stoichiometric ratios of said reactions. The reaction carrier is introduced into the reactor in an amount defined with respect to the total weight of the reagents so that it can perform a modulator function.
