Equimolar proportions of dodecamethylene diamine and naphthalene-2,7-dicarboxylic acid were dissolved in water, and then methanol was poured into the solution to form dodecamethylene diammonium naphthalene-2,7-dicarboxylate (12-N salt). The procedure of Examples 1 to 3 was repeated except that the 12-N salt was used instead of the 6-N salt, and hexamethylene diammonium monomethylterephthalate isophthalate (6-MTIA salt) was used instead of the 6-I salt. The properties of the resulting polyamides are shown in Table 8.
