Abstract

PURPOSE: To stably obtain an aromatic polyamide having a high polymerization degree, by forming a stable prepolymer solution with a combination of an aromatic diamine(A) and an aromatic diacid halide (B) in a specific molar ratio, and by polymerizing the solution on the addition of insufficient component so as to let the molar ratio of (A) to (B) be 1: 1 as a whole.
