聚苯乙烯-N-(4-羟基苯基)-马来酰亚胺合成的研究

THE STUDY OF THE SYNTHETIC METHODS OF POLY [STYRENE-ALT-N-(P-HYDROXYPHENYL) MALEIMIDE]

为了比较合成方法,找到最佳的合成线路,本文从三条合成路线来探讨聚苯乙烯-N-(4-羟基苯基-马来酰亚胺的合成。元素分析表明共聚物组成为1:1;通过NMR、IR和UV,我们分析了共聚物的结构;通过DSC和TGA分析了共聚物的热性能;当_n=5.8×10~4时,玻璃化温度为257℃。

To compare the synthetic methods and find the optimum synthetic route,three routes were tried to prepare the Poly [stytene-alt-N- (p-hydroxyphenyl) maleimide] (MR-O) .The co-polymer composition was close to 1 : 1 ,as deterimined by elemental analysis. By using NMR, IR and UV, the chemical structure of the copolymer was analysed. The thermal properties of the copolymer were investigated by differential scanning colorimetry and thermal gravimetric analyses, When Mn =5.8×104, the glass transition temperature of the copolymer reaches 257℃.
