摘要 本文以2-溴异丁酸季戊四醇四酯（PT-Br）为引发剂，CuBr为催化剂，五甲基二亚乙基三胺（PMDETA）为配体，引发荧光单体4-乙烯基二苯乙烯（VS）进行原子转移自由基聚合。合成了星型荧光聚合物，且分子量分布较窄（1．37—1．50）。通过与线性聚4-乙烯基二苯乙烯（line-PVS）的性能比较，发现星型聚4-乙烯基二苯乙烯的溶液粘度和玻璃化转变温度都相对较低。另外，还通过荧光光谱对星型聚合物的光学性能进行了表征。 Star-shape fluorescent poly （4-vinyls）stilbene （PVS） was synthesized by the Atom transfer radical polymerization （ATRP） with pentaerythritol tetrakis（2-bromoisobutyrate）（PT-Br） as initiator, CuX as catalyst,PMDETA as ligand and 4- vinylstilbene（VS） fluorescent monomer, respectively. The ＂living＂ radical polymerization of 4-vinylstilbene（VS） can be controlled effectively with the low PDI（ 1.37 - 1.50）. The star PVS exhibited a lower viscosity and glass transition temperatures as compared to its linear counterpart. Moreover,the optical properties of the star-shaped PVS have been characterized by fluorescence.
