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.

Abstract: This document describes biochemical pathways for producing 2,4-pentadienoyl-CoA by forming one or two terminal functional groups, comprised of carboxyl or hydroxyl group, in a C5 backbone substrate such as glutaryl-CoA, glutaryl-[acp] or glutarate methyl ester. 2,4-pentadienoyl-CoA can be enzymatically converted to 1,3-butadiene.
