Abstract

PURPOSE: To provide a polyamide composition giving a molded product having a good appearance and excellent fire resistance, by a method wherein melamine and cyanuric acid are separately molten and mixed with a polyamide, and then both mixtures are molten and mixed with each other.
CONSTITUTION: A molten mixture of melamine and a polyamide, and a molten mixture of cyanuric acid and a polyamide and mixed proportion to provide an equal mole of melamine and cyanuric acid. The effect of this method comes from easy reaction of melamine and cyanuric acid in molten state to form melamine cyanurate. The reason for easy reaction seems to be due separate melting and mixing of melamine and cyanuric acid with a polyamide resin, which enhances compatibility of both. A preferable temperature for melting and mixing is a temperature 5W80°C higher than m.p. of polyamide resin used.
