Chromium based single‐site catalysts allow the production of ultra‐high molecular weight polyethylene with very high productivities. The picture shows a donor‐functionalised indenyl chromium catalyst in action where a strong electron‐donating substituent leads to an increase in catalytic activity and co‐monomer incorporation. The correlation between donor strength, electronic and catalytic properties was studied systematically. More information can be found in the Full Paper by M. Enders et al. (DOI: 10.1002/chem.202101586).
