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.

关 键 词:原子转移自由基聚合  星型聚4-乙烯基二苯乙烯  性能

Abstract: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.
Keywords:ATRP  star poly(4-vinyls)stilbene  fluorescence
