摘要
以氯甲基甲醚为氯甲基化试剂,氯化锌(ZnCl2)为催化剂,对聚芳醚砜(PSF)进行氯甲基化反应.通过改变反应时间、催化剂用量及反应温度等来探讨聚芳醚砜氯甲基化反应的最佳条件.合成的聚合物结构由1H NMR得到确认,其热学性能通过热重分析(TGA)、示差扫描量热法(DSC)测试,并考察了其溶解性能.
The chloromethylation of polysulfone was synthesized by using the chlorine methyl ether as the chlorine methylation reagent and adopting ZnCl2 as catalysts.The chloromethylation ratios were controlled by changing the reaction time,the amount of catalyst and the reaction temperature.The polymers obtained were characterized with 1H NMR method.The thermal stability of the polymer was investigated by thermogravimetric analysis（TGA） and differential scanning calorimetry（DSC）.Its solubility was also studied.
