| 摘 要： | 利用反应的放热量变化来衡量反应速度,对氯化聚乙烯(CPE)固相法合成氯磺化聚乙烯(CSM)反应中的表观活化能进行了研究,提出了一种近似计算表观活化能的方法。计算结果表明,该反应的表观活化能Ea较低(9.12kJ/mol),因此CPE固相法合成CSM可以在较低的温度下进行。

| Abstract: | The apparent activation energy of chlorosulfonation reaction of chlorinated polyethylene(CPE) was studied for the synthesis reaction of chlorosulfonated polyethylene(CSM) from CPE in the solid state. The change of reaction heat was used to measure the reaction speed. A method was proposed for approximately calculating the apparent activation energy. The result indicated that the apparent activation energy was low( E a=9 12 kJ/mol), and the chlorosulfonation reaction of CPE by solid phase could be carried out at low temperature. |
