摘　　要：以4-羟基二苯甲酮为原料制备了4,4-二羟基四苯基乙烯,再与丙烯酰氯反应,合成了含有可聚合双键的4,4-二丙烯酸酯四苯基乙烯(TPE)。在引发剂BPO的作用下,所得产物与甲基丙烯酸甲酯(MMA)反应,制备了PMMA-r-PTPE共聚物。采用红外光谱、核磁共振和X射线衍射等方法,对制备的PMMA-r-PTPE共聚物进行了结构表征,测得聚合物的荧光发射波长为463nm,相比原料4,4-二丙烯酸酯四苯基乙烯,出现了不同程度的蓝移,而且都产生了荧光。对共聚物进行热重分析后发现,产物在336℃时发生了分解,说明共聚物PMMA-r-PTPE具有很好的热稳定性。In this paper,4,4-dihydroxytetraphenylethylene was synthesized from 4-hydroxybenzo-phenone by modified McMurray reaction.Then acryloyl chloride was added to form tetraphenylethylene compound containing polymerizable double bonds.PMMAr-PTPE copolymer was prepared by free radical reaction between the product and methyl methacrylate.The structure of PMMA-r-PTPE copolymer was determined by infrared spectroscopy,nuclear magnetic resonance and X-ray diffraction.The results showed that PMMA-r-PTPE copolymer was successfully synthesized.The fluorescence emission wavelength of the copolymer was 463 nm by fluorescence spectroscopy,and blue shift was observed relative to the raw material 4,4-diacrylate tetraphenylethylene.The thermal stability of the copolymer was analyzed by thermogravimetric analyzer(TG).It was found that the copolymer decomposed at 336℃,indicating that it had good thermal stability.
