Abstract
In this study, various chain lengths of 1' isosorbide (IC 22, IC 32, IC 52, IC 102, IC 29, IC 39, IC 59, IC 89) was prepared from isosorbide and ethylene oxide or propylene oxide in the presence of K2CO3. The successful synthesis of 1' isosorbide (IC 22, IC 32, IC 52, IC 102, IC 29, IC 39, IC 59, IC 89) was confirmed by 1H-nuclear magnetic resonance (1H-NMR). Bio-based high elastic polyurethanes were made using polycaprolactone diol, various chain lengths of 1' isosorbide and hexamethylene diisocyanate. The polyurethanes were produced by one-shot bulk polymerization without catalyst. The successful synthesis of the polyurethanes was confirmed by FT-IR and GPC. The thermal and mechanical properties were characterized by thermogravimetric analyzer (TGA), differential scanning calorimetry (DSC). The mechanical properties were measured using universal testing machine (UTM). Degradation test was performed using PBS solution and biocompatibilities of PUs were tested using C2C12 for biomedical applications.Biography
