摘要/Abstract

摘要： 本文以聚醚醚酮和聚醚砜两种齐聚物为原料合成了聚醚醚酮/聚醚砜嵌段共聚物,用动态力学谱仪对其进行了动态力学性能研究。从无定形共聚物样品对数减量-温度谱图中观察到清晰而完全分离的玻璃化转变内耗峰和非晶态向结晶态转变(α‘转变)内耗峰,确认α'转变发生在冷结晶初期而后很快减弱。

Abstract: Polvetheretherketone/polyethersulfone block copolymers were prepared by condensation of two oligomers and their dynamic mechanical behaviour were investigated.Two ditstinct relaxation peaks i.e.βand α',were observed in amorphous copolymer samples and it was found that the α' relaxation can be attributed to low temperature crystallization of PEEK.
