摘    要:以季戊四醇、1,2,4-偏苯三甲酸酐和环氧氯丙烷为原料,合成超支化聚合物,利用合成聚合物分子外围的羧基与亚硫酰氯反应使其分子外围的羧基酰氯化,通过傅-克酰化反应将苯乙烯引入到超支化聚合物分子末端,得到末端含苯乙烯结构的超支化荧光聚合物。采用红外光谱、热分析及荧光光谱等手段表征了聚合物的结构,研究了其热稳定性及荧光性能与结构的关系。将苯乙烯接到超支化聚合物分子外围得到的聚合物具有较好的热稳定性,其荧光特性表现为:激发波长为254nm时,其发射光谱的峰值为500nm~506nm;激发波长为365nm时,其发射光谱峰值在361nm~365nm。

关 键 词:超支化  荧光聚合物  合成  性能

Abstract:Hyperbranched polyester was prepared via the reaction of 1,2,4-trimellitic anhydride,epichlorohydrin and pentaerythritol with pentaerythritol as core.The carboxyl group of the polymer was transformed into carboxyl chloride by reacting it with thionyl chloride.Then hyperbranched fluorescence polymer was synthsized by introducing styrene to the chain terminal of the hyperbranched polymer via Friedel-Crafts acylation.The structure,thermal stability and relationship between fluorescence properties and structure...
Keywords:hyperbranched polymer  fluorescent polymer  synthesis  performance
