Abstract
Flame-retarding polyamide composition having excellent mechanical and flame retardant properties is disclosed. The composition comprises polyamide, about 3 to 40% by weight of melamine on the basis of the polyamide, and about 0.5 to 20% by weight on the basis of the polyamide and about 2 to 75% by weight on the basis of melamine of a compound represented by a compound selected from the group consisting of the following formulas (I) and (II) ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are the same or different radicals selected from the group consisting of hydrogen, alkyl, alicyclic and aromatic radicals having from 1 to 10 carbon atoms, and from such radicals having a substituent selected from the group consisting of --OH, --COOR' and --CONH.sub.2, wherein R' is aliphatic alkyl group having from 1 to 5 carbon atoms.
