## Abstract Experiments designed to prepare Ziegler‐Natta catalysts with controlled particle morphology are reported. Different dealcoholation processes are used on the adduct MgCl~2~ · __n__EtOH to prepare the catalysts: either thermal treatment or chemical dealcoholation employing different subst
## Abstract An ethylene–propylene copolymer synthesized with a Ziegler–Natta catalyst was fractionated by a combination of dissolution/precipitation and temperature‐gradient extraction fractionation. The fractions were characterized with ^13^C‐NMR, differential scanning calorimetry, and wide‐angle
