An array of road signs indicating no parking, no entry, and parking make it clear for the bound polymeryl group which quadrant it should occupy. In their Communication on page 3529 ff., M. Kol et al. describe how the combined action of electronic and steric effects in octahedral polymerization catalysts controls enantiofacial monomer insertion, thus leading to ultra‐highly isotactic polypropylene.
