It was discovered that when ethyl nitrite was introduced to the surface of catalyst, Pd ethoxyl compound was formed and simultaneously the active site Pd was transferred to the surface of catalysts with the change from Pd〓 to Pd〓. Then lined-adsorbed CO inserted into Pd alkoxyl compound to form the carboethoxypalladium complex.

研究结果表明，在CO偶联反应过程中，亚硝酸乙酯在催化剂上吸附，生成钯乙氧基络合物，同时将催化剂表面上的活性中心氧化，由Pd〓→Pd〓，并向催化剂表面上迁移。

A series homopolyme of ethylene synthesised by metallocene catalyst was analyzed by the high temperature gelatin permeation chromatography. The results showed that the molecular weight distribution changed not too much when the ratio of Al/Ti ranging between 1000 and 4000, while the molecular weight distributed increased from 2.48 to 2.81 when the ratio ranging between 4000 and 7000; catalyst D had the lowest activity to be used as asymmetric metallocene catalyst; the curve of molecular weight moved much to the left with the increases of temperature and two active centres appeared when the temperature is 70℃.

通过高温凝胶渗透色谱对茂金属催化合成的一系列乙烯均聚物进行了分析，可以看出Al/Ti比从1000变到4000时，分子量分布曲线图变化不大，而从4000变到7000时，变化相当大，分布宽度从2.48增至2.81；催化剂D的活性最小，可作为非对称性茂系金属催化剂；该聚合体系分子量的大小受聚合温度的影响很明显，随温度的升高，分子量分布曲线图向左发生很大位移，在聚合温度为70℃时存在两个活性相当的活性中心。
