Properties of Castor Oil/Plucaprolactone Based Polyurethane for coating material |
| 초록 |
Castor oil and polycaprolactone (PCL) were used as the biorenewable feedstocks for polyurethane. The castor oil/PCL based polyurethane was prepared by the one-step polymerization process with different castor oil contents. The PCL and MDI acted as soft and hard segments, respectively, and castor oil acted as dendritic point in the PCL/castor oil based polyurethane structure. The chemical structure, crystallinity and molecular weight of synthesized castor oil/PCL based polyurethane were investigated. The molecular weight and crystalline peak intensity of castor oil/PCL based polyurethane were decreased with increasing castor oil contents because PCL contents with higher molecular weight were decreased relatively with increasing castor oil. The enzymatic biodegradation and shape memory properties of castor oil/PCL based polyurethane were also investigated. This research was supported by National Research Foundation of Korea.
