DOI: 10.1039/C5DT01514F, PaperR. Cipullo, P. Melone, Y. Yu, D. Iannone, V. Busico
Despite decades of thorough mechanistic investigations, it is still hard to predict the activity of a novel olefin polymerisation catalyst, even when the precursor is a well-defined molecular entity. Kinetic studies using quenched-flow methods can help to understand why.
