In this study, controlled preparation of polyols with primary hydroxyl and ethylene oxide functionalities are attempted through thiol-ene click coupling reaction between vegetable oil (VO) and different kinds of thiol-containing compounds. Experimental parameters, such as concentrations of chemicals, reactions time, and reaction temperature, were carefully optimized to improve reaction efficiency and to control the structural characteristics of the polyols. 1H-NMR, GPC, MALDI-TOF, and titration methods were employed to investigate the structures and functionalities of the polyols. The resulting VO-based polyols were successfully introduced into thermoplastic polyurethanes (TPUs). Thermal, mechanical, shape memory, and cytotoxicity evaluation of the TPUs were performed. |
