Industrial Ziegler–Natta catalysts for polypropylene production are complex formulations with a reputation for being “black boxes”. In this paper, we report the results of an extensive investigation of the three latest commercial generations, performed with advanced high-throughput experimentation tools and methods. The thus obtained database of structure–property relationships, of extraordinary width and depth, provided a high-definition picture of the screened systems, allowing us to highlight important details of their inner workings. In particular, the delicate relationship between surface coverage and lateral steric pressure on the stereoselectivity of the catalytic species, as well as the role of chemisorbed donor and Al-alkyl species on said parameters for different formulations, was revealed.

揭开齐格勒-纳塔催化剂的神秘面纱:立体选择性的起源
用于聚丙烯生产的工业Ziegler-Natta催化剂是复杂的配方,以“黑匣子”而闻名。在本文中,我们报告了使用先进的高通量实验工具和方法对三个最新的商业世代进行的广泛调查的结果。如此获得的具有非同寻常的宽度和深度的结构-属性关系数据库,提供了已筛选系统的高清图片,使我们能够突出显示其内部工作的重要细节。特别地,揭示了表面覆盖率和横向空间压力对催化物种的立体选择性之间的精细关系,以及化学吸附的供体和Al-烷基物种在所述用于不同配方的参数上的作用。
