【摘要】 <正>热塑性聚醚酯弹性体是由可结晶的硬段和易形变的软段组成的嵌段聚合物。通过改变软硬段的组成、含量可以调控材料的物理机械性能。聚酯酰亚胺聚醚热塑性弹性体是将酰亚胺官能团引入到聚醚酯嵌段共聚物的主链中,利用聚酯酰亚胺链段刚性大,分子间作用力强的特点,合成的一种耐高温热塑性弹性体。由于软链段的玻璃化温度低,常温下处于高弹态,受到应力后很容易更多还原

【Abstract】 Series of poly(ester-imide-ether) thermoplastic elastomer with hard and soft segment were prepared via melt polyconzation with the imide acid from 1,2,4-benzenetricarboxylic(TMA) and 4,4′-oxydianiline(ODA),1,6-Hexanedio and Polyoxytertrambthyl Glycol(PTMG1000).The structure and properties of imide acid and thermoplastic elastomers were characterized by FT-IR,~1H-NMR spectroscopy and DSC.The results indicate the polymers have good thermo properties.Introducing of polyether decreases the melt point and increases the solubility of polymer respectively.更多还原
