摘要
以双酚A和溴丙炔为原料,采用相转移催化剂,合成了二丙炔基双酚A醚。利用红外、核磁对其结构进行了表征。并以此为原料,制备了二丙炔基双酚A醚的聚合物,利用TG-DTG研究了该聚合物的热分解动力学,并计算了动力学参数。用Kissinger法和Ozawa法求得的聚合物热分解活化能分别为166.36kJ.mol-1和199.90kJ.mol-1;用Coats-Redfern法求得聚合物的热分解反应为一级反应。在氮气气氛中,聚合物维持60s寿命的最高使用温度为461℃。
Dipropargyl ether of bisphenol A was synthesized by using phase transfer catalyst and was characterized by FT-IR,^1H NMR and ^23C NMR. A polymer of dipropargyl ether of bisphenol A was prepared. TG and DTG were used to study the thermal degradation kinetics of the polymer in N2. The kinetic parameters were calculated by methods of Kissinger and Ozawa. The results showed that the apparent degradation reaction order of the polymer of dipropargyl ether of hisphenol A was 1 in N2 via the Coats-Redfern method. Thermal degradation activation energies of the polymer were 166.36 kJ·mol^-1 and 199.90 kJ·mol^-1 by methods of Kissinger and Ozawa respectively. The temperature of 60 s lifetime was 461℃ in N2.
