Abstract
The invention relates to a flame-retardant polyamide composition comprising a polyamide with a melting temperature higher than 265° C. and ammeline and/or ammelide, in which the ammeline and/or ammelide is obtainable by a biocatalytic process from melamine in an aqueous reaction mixture comprising a biocatalyst, wherein melamine is converted into ammeline and optionally further into ammelide.
