This content is a preprint and has not undergone peer review at the time of posting.


Manuscript on a study on a homogeneous polymerization catalyst, its conversion to a heterogeneous catalyst by reaction with a support, an improvement of catalytic properties by this step, characterization of the structure of both catalysts, and insight into the mechanism of ethylene polymerization and its relation to electronic structure of intermediates.

All important information for interpreting and reproducing the findings is contained in the main text and the supplementary information appended within the same PDF document.
