Abstract

PURPOSE: To obtain a flame-retardant polyamide composition having improved haet resistance, mechanical properties and moldability, by reacting cyanuric acid in molar excess with melamine in polymerization of a polymide.
CONSTITUTION: (A) Melamine is reacted with (B) cyanuric acid in molar excess of (A) in polymerizing a polyamide-forming monomer, e.g. ε-caprolactam, in the presence of water to give a flame-retardant polyamide composition comprising melamine percyanurate. Preferably, the molar ratio of (A) to (B) is 100:130W150, and the total content is 3W15wt%.
EFFECT: Low cost and improved economic advantage compared with the conventional process.
