Comparing Triaminononane and TREN as Trifunctional Amine Cross-Linkers in Covalent Adaptable Networks.

ABSTRACT: Primary amines are of utmost importance for the design of various polymeric materials, because of their reactivity, low cost and widespread availability. This is demonstrated by the numerous cross-linking strategies of thermosets that rely on the reaction of multifunctional amines with for example epoxides, esters or aldehydes. Tris-(2-aminoethyl)-amine (TREN) has long remained the only large-scale available, low mass trifunctional primary amine. Despite its known toxicity, significant vapor pressure and several drawbacks related to its tertiary amine functionality, including oxidation-induced coloration, reduced thermal stability and increased reactivity, TREN helped to shape the field of covalent adaptable networks (CANs). On the other hand, we anticipated that triaminononane (TAN) as an
