Metallocenes can catalyze the polymerization reaction of olefins. Prior to reaction, they require activation on the surface of solid activator particles. The active component in solid activators is methylaluminoxane (MAO). When MAO is heterogeneously dispersed over the particles, some particles have a homogeneous MAO distribution, whereas others only have an MAO‐shell. Only the homogeneous particles are capable of activating the metallocenes. Using Energy‐Dispersive X‐Ray spectroscopy, the interparticle heterogeneity can be assessed and allowing for prediction of the catalytic activity.

茂金属可以催化烯烃的聚合反应。在反应之前，它们需要在固体活化剂颗粒的表面上活化。固体活化剂中的活性成分是甲基铝氧烷（MAO）。当MAO异质地分散在颗粒上时，某些颗粒具有均匀的MAO分布，而另一些仅具有MAO壳层。仅均质颗粒能够活化茂金属。使用能量分散X射线光谱学，可以评估颗粒间的异质性，并可以预测催化活性。可以在B. M. Weckhuysen等人的《全文》中找到更多信息。在第11944页。
