二氧化碳/环氧氯丙烷共聚物的热降解动力学研究

Study on kinetics processes of aliphatic polycarbonate-CO_2/ECH copolymer by thermal analysis

二氧化碳 (CO2 )和环氧氯丙烷 (ECH)在稀土络合催化体系作用下共聚反应 ,合成出脂肪族聚碳酸酯 (ECHCO2 )。采用热重分析法研究了共聚物ECHCO2 热降解反应的动力学 ,测定了不同升温速率下共聚物的热降解过程 。

In this thesis,the rare earth coordinated catalytic system was used to catalyze the copolymerization of CO 2 and ECH.The aliphatic polycarbonate ECHCO 2 was synthesized.The TG was used to study the thermal degradation kinetics of the copolymer ECHCO 2 .The TG spectra were recorded under different heating rates.The degradation reaction order and activation energy were determined.
