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. This 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 this review along with their properties and applications in the various fields. Furthermore, the future prospects of NIPU have also been portrayed here.

不断寻求绿色和可持续的聚合材料已成为人们关注的话题。在这种情况下，与从石油资源和异氰酸酯获得的常规聚氨酯（PU）相比，非异氰酸酯聚氨酯（NIPU）材料本质上被认为是最环保且无毒的材料，并引起了广泛的关注。这篇评论文章首先强调了NIPU相对于传统PU的重要性。该评论进一步讨论了使用植物油和异氰酸酯生产的部分绿色聚氨酯（GPU）的不同合成方法的摘要。此外，为了消除异氰酸酯的缺点并生产完整的GPU，已经详细讨论了NIPU的生产。在这篇综述中，有关NIPU进步的最新文献及其在各个领域的特性和应用也进行了讨论。此外，NIPU的未来前景也在此刻画。
