Abstract
, improved melt flow) for the bio-derivable NIPUs. These findings suggested that the added functionalities (methoxy groups) derived from lignin precursors improved thermomechanical stability while also offering increased processability. Altogether, the structure-property-processing relationships described in this work can help facilitate the development of sustainable, performance-advantaged polymers.
