Facile and efficient preparation of green polyols with gradually increasing functionalities for polyurethane synthesis |
| 초록 |
Castor oil is a nonedible cost-efficient plant-oil, which is an excellent candidate for replacing petroleum based materials in polymers. Castor oil with its readily existing hydroxyl group in its triglyceride structure is an adequate base poyol in investigating the effect of degrees of crosslinking on the properties of polyurethane. In this research castor oil based polyols with gradual increasing functionalities were prepared using thiol-ene photo click reaction. The polyols prepared by facile and efficient photo-click reaction was successfully synthesized and characterized, and the increasing hydroxyl values were measured. The effect of the increasing crosslinking density and structure of the polyols on the mechanical and thermal properties of polyurethane were investigated. This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2016R1A6A1A03013422) |
