| 摘 要： | 针对聚砜—热致液晶聚合物 (PSF TLCP)共混体系相容性差的问题 ,在合成不同分子量羟基封端聚砜 (PSF -OH)低聚体的基础上 ,通过溶液缩聚反应 ,合成了以下 3类嵌段共聚物增容剂 :聚砜—对羟基苯甲酸 (PSF—PHB) ,聚砜—对苯二甲酸乙二醇酯 (PSF -PET)和聚砜—对苯二甲酸对苯二酚酯 (PSF—PHQT)。红外光谱和流变性分析表明 ,合成了具有预期结构的嵌段共聚物 ,并且所合成的嵌段共聚物包含了较长的聚酯链段。

| Abstract: | For the poor compatibilization of the polysulfone (PSF) / thermotropic liquid crystalline polymer(TLCP)blends,three kinds of block-copolymer compatibilizers,on the basis of hydroxyl-terminated polysulfone oligomers(PSF-OHs)with different molecular weights,were synthesized.The infrared spectra and rheology analysis showed that the expected copolymers were obtained,and these block-copolymer compatibilizers consisted of relatively long polyester chains. |
