A greener perspective: non-isocyanate polyurethane
The continuous quest for green and sustainable polymeric material has become a topic of interest. In this context, nonisocyanate polyurethanes (NIPU) materials are considered the best being ecofriendly and nontoxic in nature and have attracted great deal of attention as compared to the conventional polyurethane (PU) obtained from petroleum resources and isocyanates.
A new review article first highlights the importance of NIPU over the conventional PU. The review further discusses the summary of different synthetic approaches for partial green polyurethane (GPU), which was produced using vegetable oil and isocyanates. Further, to remove the shortcomings of isocyanates and to produce complete GPU, the production of NIPU has been discussed in detail.
The recent literatures on the advancement in NIPU have also discussed in the review along with their properties and applications in the various fields. Furthermore, the future prospects of NIPU have also been portrayed.
The study has been published in Progress in Organic Coatings, Volume 154, May 2021.
