摘要
2氨基苯并咪唑与苯乙烯马来酸酐共聚物 (SMA)反应 ,经脱水闭环制得聚苯乙烯马来酰亚胺聚合物 (SMI)。通过对聚合物 (SMI)红外、紫外、荧光光谱、GPC和热性能测试 ,表明其在保持了 SMA原有性能的同时 ,热稳定性有所改善 ,且具有荧光性能。研究了溶剂、p H、猝灭剂等对聚合物 SMI荧光性能的影响。
The poly(styrene co maleic anhydride)(SMA) was modified by some fluorescent organic molecules 2 amino benzimidazol to prepare the fluorescent polymers(SMI). These polymers were characterized by FT IR spectra, UV spectra, Fluorescent spectra, DSC and GPC. They not only kept the excellent properties of SMA but also possessed higher thermal stability. The influences of solvents, acidty and quenching agents on the fluorescence of these polymers were investigated. This is a convenient method to produce the fluorescent materials.
