Styrene Polymerization with Group III Metallocenes: A Generative and Interpretable Catalyst Design Strategy Combining Density Functional Theory and Machine Learning

ChemistryEurope, EarlyView.
Machine‐learning methods are used to predict styrene binding energies and insertion barriers in a series of group III cationic catalysts. A generative algorithm based on these predicted data is provided to propose new catalysts. The rational design of group III metallocene catalysts for styrene polymerization remains a complex challenge due to ...
