摘　　要：采用Brabender塑化仪、索氏抽提器、红外光谱(IR)和核磁共振波谱(NMR)初步研完了聚碳酸酯和聚对苯二甲酸乙二醇酯(PC/PET)共混体系在熔融过程中发生的酯交换反应和产物结构。结果表明,PC/PET共混体系在熔融过程中有酯交换反应发生,反应程度与组分含量、熔融温度和共混时间有关。This paper deals with the study of the ester exchange reaction and the structure of the reaction products in PC/PET melting blend system by means of Brabender Plasticor-der, Soxhlet extraction, Infrared and 13C NMR analyses. The result shows, the ester exchange reaction did take place in PC/PET melting blend system, the extent of exchange reaction depends on content of the components, mixing temperature and mixing time.
