【摘要】 采用IR技术测试了烯烃聚合Ti-Mg系负载型催化剂制备过程形成的物种,根据Si-Ci、Ti-O、C—O和C=O键特征吸收峰的变化,表征制备过程所生成的载体Bu—O—SiCl₃与MgCl₂和催化剂“预备体”与MgCl₂·TiCl₄,IR光谱的信息与聚合反应动力学的结果一致。更多还原

【Abstract】 The formed species in preparation process of Ti-Mg system supported catalyst for olefin polymerization were determined by using IR techique. On the basis of changes of characterstic absorption peak for Si-Cl、Ti-O、C-O and C=O bond, the formed Carriers Bu—O→MgCl₂—SiCl₃ or MgCl₂ and Catalyst "Precursors" Bu—O→MgCl₂—TiCl₃ or MgCl₂·TiCl₄ were characterized. The informations of IR Spectra are in agreement with the results of polymerization reaction kinetics.更多还原
