Preparation of thermoplastic polyurethanes with vegetable oil-based polyols with controlled hydroxyl functionalities |
| 초록 |
Depletion of fossil resources and environmental issues has triggered the search for renewable feedstocks for sustainable polymers. In this study, controlled preparation of polyols with predetermined hydroxyl functionalities ranging from 2 to 4 were attempted using thiol-ene click reaction between soybean oil (SO) and 2-mercaptoethanol (ME). A series of thermoplastic polyurethanes (TPUs) were carefully prepared from the SO-based polyols and their polymerization characteristics were investigated. SO-based polyols with three and four ME units afforded TPUs with hyperbranched architectures. The SO-based TPUs exhibited improved mechanical and thermal properties, demonstrating hard and tough elastomers. The TPUs also exhibited excellent shape memory properties and film transparencies. This technique affords an efficient synthetic path way for the controlled preparation of polyols and TPUs from renewable resources. |
