Abstract: A method of making a polyamide copolymer includes subjecting a reaction mixture to conditions sufficient to form the polyamide copolymer, the reaction mixture including adduct A and adduct B. Adduct A is a 1:1 adduct of a diamine having the structure H2N-R1-NH2, or a salt thereof, and an aliphatic diacid having the structure HO-C(O)-R2-C(O)-OH, or a salt thereof. Adduct B is a 1:1 adduct of the diamine having the structure H2N-R1-NH2, or a salt thereof, and an aromatic diacid having the structure HO-C(O)-R3-C(O)-OH, or a salt thereof. At each occurrence, R1 and R2 can be independently a substituted or unsubstituted (C1-C20)alkylene. At each occurrence, R3 can be independently a substituted or unsubstituted (C6-C20)arylene. The molar ratio of adduct A to adduct B in the reaction mixture can be about 61:39 to about 90:10.
