摘　　要：采用中蓝晨光化工研究院生产的聚碳酸酯(PC)树脂,与陶氏公司的商品化PC进行比较。通过红外光谱、熔体质量流动速率、GPC、热失重分析以及拉伸性能、透光率测试等分析技术,研究了晨光生产的PC树脂的结构以及加工流变性能与陶氏PC树脂的差别,在此基础上进行片板挤出工艺条件及性能的研究,并对不同的PC片材的热稳定性进行了研究。This paper was to investigate the structure and processing rheology of polycarhonate （PC） obtained from Chengrand Research Institute of Chemical Industry. PC produced by DOW Chemical was also choosed for comparation. The properties were characterized by IR, MI, GPC, TGA. Tensile property and photopermeability were measured too. At the same time, the extrude technology and the mechanical properties of PC plate were also investigated. And the thermal stability of PC plate was studied.
