    摘要： An aromatic and/or heterocyclic polyamide-amide type polar solvent composition is prepared by prepolymerizing an aromatic or heterocyclic diamine with an aromatic or heterocyclic or heterocyclic dicarboxylic acid chloride in a smaller molar equivalent than that of the diamine to prepare a prepolymer solution having a solution viscosity of 20 poise or less; by removing a by-product, hydrochloric acid, from the resultant prepolymer solution by neutralizing it with ammonia to such an extent that the pH of a mixture of 10 g of the neutralized mixture with 200 ml of water becomes 3.7 to 8.0; by high polymerizing the prepolymer with an additional amount of aromatic or heterocyclic dicarboxylic acid chloride, and; finally, by converting the entire amount of hydrochloric acid and 10 to 70% NH.sub.4 Cl in the resultant polyamide solution into an amide type polar solvent-soluble salt, with a neutralizing agent, the amount of the salt being in a range of from 5 to 95% by weight of the theoretical amount of the salt to be derived from the entire amount of the dicarboxylic acid chloride.
