用红外光潜、质谱等手段,研究了丙烯聚合载体型催化剂体系中第一给电子体邻苯二甲酸酐在该催化剂合成的初级阶段所形成的络合物的组成及结构。探讨了双酯、单酯两类给电子体对催化剂组成、活性及聚合物物理形态的影响。并对丙烯聚合载体型催化剂合成中的第一给电子体与醇形成的单酯结构进行了确认。
The composition and structure of the complex formed by the first electron donor phthalic anhydride in the initial stage of the catalyst synthesis were studied by means of infrared photoionization and mass spectrometry. The effects of diester and monoester on the composition, activity and physical morphology of the polymer were discussed. The monoester structure of the first electron donor and the alcohol in the synthesis of the propylene polymerization-supported catalyst was confirmed.
