嵌段聚酰胺酯(PEA)弹性体的制备及性能研究
Polymerization of Segmented Polyesteramide Thermoplastic Elastomers and Their Properties
【摘要】 先合成含有酰胺基的N ,N′双 (对甲酯基苯甲酰 )丁 (乙 ,己 )二胺 (简记为二甲基T4T(T2T ,T6T) ) ,并以此作为硬段 ,与聚氧丁撑 (PTMO)进行熔融缩聚 ,制得一系列TnT/PTMO嵌段聚酰胺酯 (PEA)。研究了硬段的结构 ,软段的相对分子质量对PEA性能的影响。
【Abstract】 N,N′-bis(p-carbomethoxybenzoyl)butane(and ethylene, hexamethylene) diamine (T4T and T2T,T6T-dimethyl) was synthesised firstly, then used as hard segments and polymerized together with poly(tetramethylene oxide). A series of segmented polyesteramide polymers were obtained. It was studied that how the structure of hard segment and the number average molecular weight determined the properties of obtained polymers.
