摘    要:使用正电子湮没寿命谱(PALS)技术研究了PS/PVAc、PS/PMMA这两个非极性-极性聚合物共混体系的相容性.PS与两种极性聚合物PVAc和PMMA的共混均为不相容共混物.自由体积特性结果显示,PS与PVAc共混的相容性比PS与PMMA共混的相容性好.

关 键 词:正电子湮没寿命谱(PALS)  聚苯乙烯  聚醋酸乙烯酯  聚甲基丙烯酸甲酯  相容性

Abstract:By means of positron annihilation lifetime spectroscopy (PALS), the compatibility of polystyrene (PS) / polyvinyl acetate (PVAc) and PS / polymethyl methacrylate (PMMA) blend systems have been studied. The results show that both PS/ PVAc and PS/PMMA blends are immiscible, but the miscibility between PS and PVAc is better than that between PS and PMMA.
Keywords:Positron annihilation lifetime spectra (PALS)  Polystyrene  Polyvinyl acetate  Polymethyl methacrylate  Miscibility
