Front Cover: The cover shows the superposition of ethylene polymerization rates with a Ziegler‐Natta catalyst at 4 different polymerization times. At the end of each polymerization, we measured the molecular weight distribution (MWD) and average short chain branching frequency (SCB) across the MWD using gel permeation chromatography with an online infrared detector. Deconvolution of this microstructural data using the equations shown in the figure permits the determination of average molecular weights and SCB frequencies per site type for these catalysts. Further details can be found in the article by João Soares and co‐workers on page 206.
