Abstract

PURPOSE: To provide a polyamide composition giving a molded product having an excellent fire resistance and appearance, by melting and mixing melamine and cyanuric acid in the presence of water.
CONSTITUTION: To a polyamide, an equal mole of melamine and cyanuric acid are melted and mixed in the presence of water. 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 to good compatibility of cyanuric acid and melamine because both are separately mixed with a polyamide. A preferable temperature for melting and mixing is a temperature 5W80°C higher than m.p. of polyamide resin used.
