“…Atactic PP is an important commercial product. It is used in industry as an additive in hot‐melt adhesives, a rubber extender, a bitumen modifier, a viscosity index improver for low‐temperature oils, and so on . At the present time, atactic PP is produced on the commercial scale as a byproduct in the manufacture of isotactic PP; it can be also synthesized with special metallocene and postmetallocene catalysts …”

The Ziegler catalyst, a combination of TiCl4 and Al(C2H5)2Cl, is a very poor catalyst for propylene polymerization. However, the addition of Mg(C4H9)2 to the Ziegler catalyst at a [Mg]:[Al] molar ratio < 0.5 leads to the formation of a potent catalyst system for homopolymerization of propylene. Polymers produced with the TiCl4–Al(C2H5)2Cl/Mg(C4H9)2 catalyst are mostly atactic and amorphous, their minor partially crystalline isotactic components constitute merely 5–10% of the combined polymer material. Principal advantages of the TiCl4–Al(C2H5)2Cl/Mg(C4H9)2 catalyst for the manufacture of atactic PP include high activity, low cost, and the ease of use: the catalyst is prepared in situ from three commercially available components. © 2019 Wiley Periodicals, Inc.

Amorphous atactic polypropylene (PP) with an average molecular weight of 50,000-100,000 is produced by polymerizing propylene with a ternary Ti(Oiso-Pr) 4 -AlEt 2 Cl/MgBu 2 catalyst at 30-50. Main advantages of this catalyst compared with other catalysts capable of nearly exclusively producing atactic PP (such as some heterogeneous Ziegler-Natta, metallocene and postmetallocene catalysts) are high activity, low cost and the ease of use: the catalyst is prepared in situ from three commercially available compounds readily soluble in aliphatic and aromatic hydrocarbons.
