Examples of the application of simple molecular mechanics techniques to the study of the polymerization mechanism of various types of Ziegler‐Natta catalysts are reported. Details are given on the new mechanism of enantioselectivity suggested by molecular mechanics studies. The validity of the latter, involving a “chiral orientation of the growing chain” which had never been suspected before, has been experimentally proved both for homogeneous and heterogeneous catalysis.
