| 摘 要： | 采用熔融接枝聚合的方法将含稀土铕配合物的线性不饱和聚酯Eu-ULP接枝到PP分子链上，制得新型的在UV下发射红色荧光的树脂。PP与Eu-ULP反应的扭矩时问曲线和接枝物UPP的IR分析结果表明Eu-ULP已成功接枝到PP分子链上，UPP为键合型的稀土高分子材料。荧光分析结果显示uPP具有良好的发光性能，其荧光强度随着接枝率的增加而增加，而DSC和WAXS分析结果则表明功能化基团Eu-ULP的键人起到类似成核剂的作用，有效提高PP的结晶速率，但同时也破坏了PP晶区的规整性。

| Abstract: | ULP containing rare earth complex(Eu-ULP) was grafted onto polypropylene in melt phase to get new type of functional resin which emits red fluorescence.Torque-time curves for reaction of Eu-ULP and PP and the IR analysis result of product UPP indicates that Eu-ULQ had been grafted onto polypropylene backbone successfully to produce bonding-type rare earth polymers.The fluorescence analysis result shows that UPP has nice fluorescence and their fluorescence intensity improves as grafted rate increases.Besides,DSC and WAXS reveal that the functional group Eu-ULP acts as nucleator to increase the crystallization rate effectively and destroy the integrity of crystalline as well. |
