建立了红外光谱密封操作技术,并制作了“流通式密封池”。利用催化剂的红外光谱谱带强度与聚合反应的对应关系,找出了该催化聚合体系的活性种、活性组分及变质组分。确定了一氯二乙基铝和二氯乙基铝在催化体系中的作用,同时对催化剂的红外谱图进行了初步解析。 Established infrared spectral sealing operation technology, and produced a “flow-through seal pool.” The active species, active component and metamorphic component of the catalytic polymerization system were identified by using the relationship between the intensity of the infrared spectrum of the catalyst and the polymerization reaction. The roles of monochloro diethylaluminum and dichloroethylaluminum in the catalytic system were confirmed. At the same time, the infrared spectra of the catalyst were preliminary analyzed.
