摘　　要：根据相容性理论 ,自制了几种PC与PBT的相容剂 ,讨论了相容剂对PC/PBT共混物力学性能的影响。研究表明 :加入相容剂改善了PBT与PC两相间的相容性 ,共混体系力学性能得到提高。通过红外光谱分析得知 。According to the compatibility theory, several compatibilizers were made. Effects of compatibilizers on the mechanical property and the compatibility of the blends were studied. Results showed compatibilizers in the PBT/PC blends enhanced the compatibility between two phases,so the mechanical property was improved. By using IR instrument, the transesterification can accelerate the miscibility.
