摘要： 本文报导了双酚A聚砜(B)与对苯二酚聚砜(H)两组份含量不同的嵌段共聚物的X射线衍射结果,B链的加入,使共聚物的结晶性能被破坏,B/H为0.48(摩尔比)时,所得共聚物已呈现出完全非晶相结构的特征.由IGC及DSC实验测定,表明这两种聚砜链是相容的.

Abstract: The decreasing in crystallinity of poly(hydroquinone)sulfone (H) by incorporations of poly(bis-A)-sulfone (B) blocks into the polymer chains was observaled by X-ray diffraction. The copolymers with B/Hmore than 0.48 (moiar ratio) were found uncrystallizable. The mixing heats of these copolymers with several probe-molecules, Tg's and Tm's obtained from IGCand DSCindicate that the two components are compatible.
