含磷阻燃共聚酯的合成、性能及其应用

摘要

阐述了含磷阻燃共聚酯的合成过程及物化性能和结晶性能.通过纺丝、织造试验表明,合成的阻燃聚酯切片具有良好的可纺性能,其织物的LOI值达34 %,具有广阔的应用前景.%The synthesis process,physical and chemical properties and crystallization properties of phosphonium flame-retardant copolymerization PET were described.Through spinning,weaving experiment,the results showed that the synthetic flame-retardant PET chip had good spinability,and its LOI value can reach 34%,the application prospect were wide.
