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 ,并计算出其降解反应级数和活化能
Carbon dioxide (CO2) and epichlorohydrin (ECH) copolymerization reaction under the rare earth complex catalyst system, synthesis of aliphatic polycarbonate (ECHCO2). The thermogravimetry was used to study the kinetics of the thermal degradation of the copolymer ECHCO2. The thermal degradation of the copolymer was measured at different heating rates. The degradation reaction order and activation energy
