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.
