| Abstract: | The azido- and ester-terminated GAP plasticizer products were determined and characterized by using FT-IR, 1H-NMR, GPC, and so on. The thermal stability of the products was studied by using DSC and TG-DTA. The results show that the azido, ester group and ether bond exist in the sample structures. The Tg is from -58℃ to -62℃, the decomposition temperature of azido is about 250 ℃, the peak value of main chain decomposition temperature is about 348 ℃. |
