摘　　要：磺化聚苯乙烯和聚碳酸酯共混物相容性的红外光谱研究刘杰何嘉松（中国科学院化学研究所工程塑料国家重点实验室北京１０００８０）关键词付立叶变换红外光谱，相容性，高分子共混物，离子偶极相互作用由于热力学原因，高分子对往往是不相容的．高分子共混物若要溶...The introduction of sulfonate groups into polystyrene has made polycarbonate and polystyrene partially miscible. The Tg's shift, revealed by DSC study, showed the partially miscibility between the two polymers. Infrared spectra confirmed that this miscibility was a contribution of the ion dipole interaction between polar groups in polycarbonate and the zinc sulfonate groups in sulfonated polystyrene.
