以1,2-双(4’-羧基苯基)邻碳癸硼烷和乙二醇为原料,合成出含碳癸硼烷结构的新型聚酯(简称CBR-PET),采用 FT-IR、1 H NMR 和 GPC 对其进行了表征.通过中子屏蔽实验发现 CBR-PET 具有显著的热中子屏蔽性能,随着样品中含硼量增加,热中子屏蔽性能增强;利用热分析技术研究了在Ar气氛下从室温~800℃的CBR-PET的热解行为,其起始分解温度约380℃,在800℃的残炭率高达72.9%.

A new carborane-containing polyester (abbreviated as CBR-PET)was prepared by the polycondensati-on reaction of 1 ,2-bis(p-carboxyphenyl)-o-carborane with ethylene glycol.The structures and molecular weight were confirmed by FT-IR,1 H NMR and gel permeation chromatography (GPC).The results of neutron shiel-ding experiments showed that the CBR-PET performed good slow neutron shielding ability which was enhanced with the boron contents increasing.The thermal characterizations of the CBR-PET in argon were investigated by using thermogravimetry analysis (TG)from room temperature to 800 ℃,its initial decomposition temperature was 380 ℃ and its char yields at 800 ℃ was 72.9%.
