【摘要】 用差示扫描量热法和热重法研究了热致液晶聚酯酰亚胺（ＰＥＩ）中己二胺（Ｃ６）、戊二胺（Ｃ５）以及癸二胺（Ｃ１０）组成对ＰＥＩ的相转变温度、玻璃化转变温度（Ｔｇ）和热稳定性的影响。更多还原

【Abstract】 The thermal behavior of some thermotropic liquid crystalline polyester-imideshave been examined by DSC and TGA techniques. It is found that the content of aliphatic di-amines with different chain lengths(C5 , C6 and C10)showed a definite influences on thetemperatures of glass transition and phase transition of the TLC polymers.更多还原
