Abstract
PURPOSE: To prevent deterioration and impart heat stability to a molten polyamide, by adding hydrazine to the polyamide.
CONSTITUTION: A) A polyamide consisting of repeating units of amide bonds derived from a diamine and a dicarboxylic acid is blended with B) 0.05W2wt.%, preferably 0.1W1wt.% of hydrazine (preferably hydrazine hydrate) based on the polyamide, and, if necessary, a viscosity stabilizer or an antistatic agent. Addition of an alkali metal phosphite or hypophosphite improves further heat stability. An ultraviolet light absorber, an antistatic agents, etc. are added, if necessary
