Abstract
This disclosure provides a process for removing acrolein or allyl alcohol from a polyester composition, the process comprising: combining a polyester composition derived from 1,3-propanediol with an amino amide or a primary amine; wherein the amino amide or the primary amine is combined in sufficient quantities to scavenge acrolein or allyl alcohol produced from degradation of the polyester composition. An analysis of reactions between anthranilamide (AAA) and acrolein demonstrates how amines or amino amides can scavenge acrolein from thermally processed poly(trimethylene terephthalate) and poly(trimethylene furan-2,5-dicarboxylate), and thermodynamic models are presented as guidance for matching targets with scavenging agent.
