The utilization of biomass resources in the production of bio-based or bio- recycled polyurethanes (Pit) enhances the sustainable development and eco-friendliness of PU. Herein, a series of new bio-based aliphatic polypropylene dicarboxylate) diols were synthesized using bio-based 1,3-propanediol (b...
