摘要: 用自行合成的 2-氨基噻唑 (1)、2-氨基-4-苯基噻唑 (2)、2-氨基苯并噻唑(3)等荧光小分子化合物,与商品化的苯乙烯马来酸酐共聚物 (SMA)中的酸酐基团反应,制成聚苯乙烯马来酰亚胺 (SMI),实现了SMA化学改性.在获得荧光聚合物的同时,不仅保持了原SMA的可溶性、成膜性等优点,其热性能也得到了改善.通过示差扫描量热 (DSC)、凝胶色谱 (GPC)、红外、紫外及荧光光谱等手段表征了荧光聚合物的玻璃化转变温度、分子量及结构与荧光性能关系.

关键词: SMA酰亚胺化改性, 荧光聚合物, 聚代噻唑

Abstract: Four kinds of fluorescent polymers have been prepared by chemical modification of poly(styrene co maleic anhydride)(SMA)with 2-amino-thiazole(1),2-amino-4-benzylthiazole(2),and 2 amino benzothiazole(3)respectively.These fluorescent polymers had good solubility and formed films easily like SMA.At the same time thermal stability was improved too.These polymers were characterized by GPC,DSC,FT-IR spectra and fluorescent spectra.Furthermore,the influences of solvents,concentration,acidity and substituting groups on the fluorescence of the polymers were investigated.

Key words: imide modification of SMA, fluorescence, substituted thiazole
