摘要
用红外光谱表征了环境友好磷系阻燃聚酯的结构,研究了环境友好磷系阻燃聚酯的特性粘数、DSC、氧指数、可纺性等性能。结果表明,磷系阻燃单体分子中的柔性链段亦被引入大分子主链中,使磷系阻燃聚酯的玻璃化温度(gθ)、熔点(θm)相应降低;磷系阻燃聚酯具有良好的阻燃性,当磷系阻燃单体质量分数4.5%时,磷系阻燃聚酯氧指数为32.8%。但由于侧基的空间体积较大也使磷系阻燃聚酯的结晶性有所降低,导致拉伸强度降低,实验结果表明磷系阻燃聚酯纤维的物性指标能够满足后加工要求。
Structures of environmental friendly phosphorous flame- retardant polyester were characterized through infrared spectra （IR）, the performance of its properties such as intrinsic viscosity, differential scanning calorimeter （DSC）, oxygen index （OI） and its spinnability was investigated. The results show that the flexxible segments Jn phosphorous flame--retardant monomer were also introduced into the backbone of the polyester macromolecules, which causes the decrease of the phosphorous flame -- retardant polyester glass transition temperature （θg） and melting transition temperature （θm）. The synthesized phosphorous flame--retardant polyester resins have a very good flame retardantability and spinDability; when the mass fraction of phosphorous flame- retardant monomer was 4. 5%, the oxygen index of phosphorous flame relardanI polyester reached to 32. 8%. The tensile strength and crystallinity decreased owing to the much more space volume of phosphorous flame-retardant polyester. The results indicate that the properties for phosphorous flame-retardant polyester can satisfy the requirements for the manufacture of polyester fibers.
