摘    要:以聚乙烯醇(PVA)和对硝基苯甲醛为原料,二甲基亚砜为溶剂,对甲基苯磺酸为催化剂,采用均相工艺合成得到聚乙烯醇缩对硝基苯甲醛(PVPNB)。通过衰减全反射-傅里叶红外光谱(ATR-FTIR)、紫外可见光谱(UV-Vis)、核磁共振氢谱(1H NMR)等测试手段对聚乙烯醇缩对硝基苯甲醛结构进行了表征。利用差示扫描量热仪(DSC)测定了聚乙烯醇缩对硝基苯甲醛的玻璃化温度(Tg)。采用差热分析(DTA)和热重分析(TGA)对聚乙烯醇缩对硝基苯甲醛热稳定性进行研究。DSC结果表明,聚乙烯醇缩对硝基苯甲醛的玻璃化温度为160 ℃。DTA和TGA结果表明,聚乙烯醇缩对硝基苯甲醛具有较好的热稳定性。

关 键 词:聚乙烯醇  聚乙烯醇缩对硝基苯甲醛  合成  结构表征  热稳定性

Abstract:Poly(vinyl alcohol)(PVA)was modified by aldehyde acetal reaction with p-nitrobenzaldehyde to obtain poly(vinyl p-nitrobenzal)(PVPNB). The structure of PVPNB was characterized by UV-Vis,FTIR and 1H NMR. The glass-transition temperature of PVPNB was evaluated by differential scanning calorimetry(DSC)and the thermal stability of PVPNB was tested by differential thermal analysis(DTA)and thermogravimetric analysis(TGA). DSC traces showed that polymer PVPNB had one single glass transition temperature at 160 . DTA and TGA curves proved that PVPNB had good thermal stability.
