Abstract
PURPOSE: To obtain economically highly-viscous polyamide having excellent quality stability, by melt-polymerization of a polyamide-forming compound in the presence of 1,6,11-triaminoundecane and a dicarboxylic acid.
CONSTITUTION: A polyamide-forming compound is subjected to a melt-polymerization in the presence of 0.05W5wt% (based on the polyamide-forming compound) 1,6,11-triaminoundecane and an almost equimolrar amount (based on 1,6,11-triaminoundecane) of a dicarboxylic acid. The polyamide-forming compound used includes ε-caprolactam, 6-aminocaproic acid, hexamethylenediammonium adipate, etc., and 1,6,11-triaminoundecane can be manfuactured industrially at low cost by reduction of bis (aminopentyl) ketone, 7-(5'-aminopentyl)-3,4,5,6-tetrahydro-2H- azepine, etc.
