Zusammenfassung:A method for producing flame resistant synthetic polyamides, suitable for spinning is described, wherein melamine and isocyanuric acid are reacted in an aqueous environment at the melamine isocyanurate formation temperature. An aqueous suspension of melamine isocyanurate is obtained having a maximum granule size not exceeding 2 microns, substantially free from agglomerates. The suspension is admixed with the monomeric material and the whole is submitted to polymerization. The invention provides a successful method for obtaining flame-resisting polyamide fibers and yarns owing to the presence therein of the melamine isocyanurate additive.
