Effect of Regioisomerism on Processability and Mechanical Properties of Amine/Urea Exchange Based Poly(urea-urethane) Vitrimers
Source abstract
Abstract
In this paper, three analogous poly(urea-urethane) elastomers were thoroughly characterized to determine the effect of regioisomerism on the processability and mechanical properties of the final materials. The polymers were synthesized starting from the same isocyanate-terminated polyol and the three positional isomers of phenylenediamine hardener. The main differences on the supramolecular hydrogen-bond network, as well as on the outcome of the dynamic amine/urea exchange reaction, were determined by experimental measurements (FTIR, rheology, DMA, tensile tests) and molecular quantum chemical calculations.
