Abstract
A promising approach for CO2 utilization is the copolymerization of CO2 and propylene oxide (PO) to prepare biodegradable polycarbonates. In particular, copolymers from CO2 and PO have potential applications as polyols in the polyurethane industry, offering new opportunities for value-added CO₂-based polymers. In this study, CO₂-based polyols with tunable carbonate contents ranging from 0~50 wt% are synthesized and subsequently employed to prepare thermoplastic polyurethanes (TPUs). The effects of carbonate content on the thermal and mechanical properties of the resulting TPUs are systematically investigated. Increasing the carbonate content lead to a gradual increase in the glass transition temperature and mechanical performance of the TPUs. Our results suggest that precise control over the carbonate content in CO₂-based polyols provides an effective strategy for tailoring the properties of TPUs, highlighting the potential of CO₂-based polyols for sustainable polyurethane materials.
