Abstract
PURPOSE: To produce a polyamide compsn. which produces molded articles having good heat resistance and mechanical properties, by a method wherein an arom. diamine is reacted with an arom. diacid chloride to produce a prepolymer, and a prepolymer solution having a specified viscosity is reacted with the arom. diacid chloride to produce a polymer.
CONSTITUTION: An arom. diamine is reacted with less than an equivalent amount of an arom. diacid chloride in an amide-type polar solvent. HCl of the resulting prepolymer soln. obtd. by the primary polymn. is neutralized with NH3. The soln. is filtered. The filtrate contg. the prepolymer is reacted with the arom. diacid chloride. HCl in the resulting polymer soln. contg. arom. polymide having high degree of polym. obtd. by the secondary polymn. is neutralized to obtain an arom. polyamide compsn. The reaction is controlled so that the viscosity of the prepolymer soln. obtd. by the primary polymn. is not more than 50 poises (at 50°C), and that the amount of a soluble salt (a solubilizing agent) in the arom. polyamide compsn. is 5W95wt% of the amount of the solubilizing agent calculated based on the sum of the acid chloride used in the primary and the secondary polymn.
