Non-isocyanate polyurethanes enjoy an increasing interest by both academia and industry.  This is not only because of  health and environmental concerns associated with the use of isocyanates and phosgene, but also because of some unique properties of these materials that can only be obtained with non-isocyanate chemistries.  NIPUs can also be made 100% from renewable materials and can be CO2 ‘negative’.
