Study on Synthesis and Characterization of Photo- and Thermal Curable Radical Initiators based on O-imino isourea |
| 초록 |
Three kinds of the photo- and thermal curable radical initiators, DicyheDCC, CyhephDCC, and BnphDCC, based on O-imino isourea were systemically designed and synthesized. The synthesized radical initiators were evaluated in acryl monomer under photo- and thermal conditions. BnphDDC with two phenyl groups showed high efficiency in photo-curing. On the other hands, DicyheDCC consisting of two cyclohexyl groups showed the lowest radical initiation temperature as Tpeak 82 oC among synthesized radical initiators. These behaviors have been simulated via density functional theory (DFT) and it indicates that the aliphatic ring had a lower enthalpy than the aromatic ring on N-O bond energy. In conclusion, this study exhibited CyhephDCC and BnphDCC based on O-imino isourea have possibilities to be applied in the photo- and thermal cure system. |
