| 摘 要： | 制备了一种新型的含磷阻燃剂-2-羧乙基苯基次膦酸(CEPPA),并用FTIR、HNMR表征了其结构。当磷含量为0.6wt%时,其阻燃共聚酯的LOI可达29.4%。同时利用DSC、TGA研究了不同磷含量共聚酯的热性能。结果表明,共聚酯的玻璃化转变温度(Tg)、熔点(Tm)、热结晶温度(Tmc)、起始分解温度(Tid)随着磷含量的增加而降低,而冷结晶温度(Tcc)、最大分解速率(Tmax)、燃烧后炭层含量则随之增加。为了更好地解释阻燃剂的阻燃机理,利用FTIR研究了TGA测试后生成炭层的结构,结果表明燃烧后的炭层主要由含磷碎片组成。

| Abstract: | A novel reactive phosphorus-containing monomer,2-carboxyethyl(phenylphosphinic)acid(CEPPA)and corresponding phosphorus-containing copolyesters were synthesized and characterized by FTIR,1H NMR spectra.The copolyester,which contains 0.6 wt % phosphorus,can reach a limiting oxygen index(LOI)value of 29.4%.The thermal properties of phosphorus-containing flame retardant copolyesters were investigated by differential scanning calorimeter(DSC),thermogravimetry(TG)under air and nitrogen.DSC shows that the glass-tr... |
