利用Zn-Fe(III)双金属催化剂(DMC)催化合成了CO2、环氧丙烷(PO)和邻苯二甲酸酐(PA)三元共聚物(PPCPA)。研究结果表明:PA参与了三元共聚反应,并且共聚物中CO2的含量为54.27%;PPCPA的降解分2个阶段进行,在升温速率分别为5、10、15、20 K/min的条件下,其第1阶段最快降解温度分别为240.9、256.3、264.1、268.3℃,第2阶段最快降解温度分别为309.9、319.6、325.8、328.5℃;通过Kissinger方程可计算出PPCPA热降解反应动力学参数,其第1阶段、第2阶段热降解反应表观活化能分别为105.801、201.907 kJ/mol,指前因子分别为1.319×1010、1.574×109min-1。
CO2, propylene oxide (PO) and phthalic anhydride (PA) terpolymer (PPCPA) were synthesized by Zn-Fe (III) bimetallic catalyst (DMC). The results show that: PA participates in the terpolymerization, and the content of CO2 in the copolymer is 54.27%. The degradation of PPCPA is carried out in two stages. Under the conditions of 5, 10, 15, 20 K / min heating rate , The fastest degradation temperature of the first phase was 240.9,256.3,264.1,268.3 ℃, the fastest degradation temperature of the second phase were 309.9,319.6,325.8,328.5 ℃ respectively; through Kissinger equation can be calculated PPPPA thermal degradation kinetics The parameters, the first stage, the second stage of the thermal degradation reaction apparent activation energy were 105.801,201.907 kJ / mol, finger pre-factor were 1.319 × 1010,1.574 × 109min-1.
