Abstract
PURPOSE: To obtain the titled polyamide with excellent flame retardancy and mechanical porperty, contg. an org. addn. salt, by the polymn. of an equivalent of an org. acid cpd., an equivalent of an org. basic cpd. and a polyamide-forming monomer by heating in the presence of water.
CONSTITUTION: An org. acid cpd. (A) e.g., 4-carboxyoxazole, 4-carboxypyrazole or 5-carboxypyrimidine), an org. basic cpd. (B) (e.g., oxazole, pyrazole or pyrimidine) in amt. strictly requried for the formation of an addn. salt with the component A, and a polyamide-forming monomer (C) (e.g., ε-caprolactam) are mixed in such a proportion as to contain about 2W25wt% org. addn. salt from the component (A) and the component (B) in the final product. Then the purpose flame- retardant polyamide is obtd. by the polymn. of the resulting mixt. by heating in the presence of at least 5wt%, based on the component (C), of water.
