Catalytic Production of Olefin Block Copolymers via Chain Shuttling Polymerization
TL;DR: A catalytic system that produces olefin block copolymers with alternating semicrystalline and amorphous segments by varying the ratio of α-olefin to ethylene in the two types of blocks is reported, which maintains excellent elastomeric properties at high temperatures.

Stereospecific Olefin Polymerization with Chiral Metallocene Catalysts
TL;DR: In contrast to heterogeneous Ziegler-Natta catalysts, homogeneous metallocene-based catalysts as discussed by the authors allow efficient control of regio-and stereoregularities, molecular weights and molecular weight distributions, and comonomer incorporation.

Polymerization of Propene and Butene with a Chiral Zirconocene and Methylalumoxane as Cocatalyst
TL;DR: In this article, the chiral ethylenebis(4,5,6,7-tetrahydro-lindeny1)zirconium dichloride is used in combination with methylalumoxane ([AI(CH3)-O],) as cocatalyst, highly isotactic polypropylene is obtained.

Oscillating Stereocontrol: A Strategy for the Synthesis of Thermoplastic Elastomeric Polypropylene
TL;DR: The isotacticity of the polymer increases with increasing propylene pressure and decreasing polymerization temperature to produce polypropylenes with an isotactic pentad content ranging from 6.3 to 28.1 percent.

Ziegler-Natta catalysis III. Stereospecific polymerization of propene with the catalyst system TiCl3AlEt3
E.J Arlman,P Cossee +1 more
TL;DR: In this paper, the stereospecificity of the polymerization of propene under the influence of α-TiCl 3 and alkyl aluminum compounds is explained based on quantum chemical principles and the crystal chemistry of transition metal trichloride layer structures.
