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。
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.
