In order to understand miscibility of UPRs/Modar blends after cured. We used Dynamic Mechanical Analysis (DMA) to approached the Network Aggregate structure and used Scanning Electron Microscopy (SEM) to observe the fractured surfaces of UPRs/Modar blends. On the other hand, the behavior of thermal decomposition of UPRs/Modar blends were studied using Thermal Gravity Analysis (TGA). The combustibility analysis was carried out using NBS smoke density test to study smoke evolution. On the other hand, for analysis of CO gas and Heat Release Rate (HRR) on the combustion procedure, using Cone Calorimetry Dynamic Flammability Evaluation System under 579℃ to research emission of CO gas and variance of HRR of UPRs/Modar blends. The modified unsaturated polyester used synthetic method that reaction with dicyclopenetadiene. The reaction temperature of modified DCPD unsaturated polyester forecast by estimation of the DSC-dynamic scanning. The flame-resistant properties of modified DCPD unsaturated polyester can by using NBS smoke density test under non-flaming process and using Cone Calorimetry Dynamic Flammability Evaluation System.
