A polyamide having a viscosity of between about 20 and about 40 FAV and a number average molecular weight of between about 9,000 and about 16,000 grams per mole is provided. The polyamide also includes un-terminated endgroups, where a difference between a concentration of carboxylic acid endgroups and a concentration of amine endgroups is about 5 meq/kg or less. |
