TPU/POE共混体系相分离过程的ATR-FTIR研究

Studies on TPU/POE’s phase separation by ATR-FTIR

  • 摘要: 探讨了一种新的共混体系热塑性聚氨酯(TPU)/聚乙烯-辛烯共聚物(POE)共混体系相分离过程中的衰减全反射傅里叶变换红外光谱(ATR-FTIR),结果发现:对于不相容TPU/POE体系,基本随着热老化时间的增加,ATR-FTIR特征峰面积也逐渐增加(温度较低除外),而温度较高时则会先增加后降低;而PU/POE/POE-g-MA体系,由于相容剂的加入,ATR-FTIR特征峰面积则随着热老化时间的增加而逐渐降低.

     

    Abstract: The process of phase separation for a new thermoplastic polyurethane/poly (ethylene-octene) (TPU/POE) blending system was studied by Fourier Transform Attenuated Total Reflection Infrared Spectroscopy (ATR-FTIR). The results show that, for the incompatible TPU/POE system, the area of characteristic peak on ATR-FTIR increased with the increase of thermal aging time (except at quite low temperatures), while it increased first and then decreased at higher temperatures. For a PU/POE/POE-g-MA system, the area decreased due to the addition of compatibilizers.
