50th Anniversary Perspective: Living Polymerization—Emphasizing the Molecule in Macromolecules [PDF]

open access: yes, 2017
The ideal of living polymerization has defined research in polymer chemistry over the past 50 years. In this Perspective, we present the case that this concept has enabled the treatment of polymers as organic molecules, rather than impure mixtures of ...

Ziegler-Natta catalyst alteration

open access: yes, 2017
Ziegler-Natta (ZN) catalysts are among the most important catalysts for the industrial production of plastics. The main components of ZN catalysts are TiCl4 in combination with an organic aluminum component as a cocatalyst, whereas a wide range of additional components exists which influence the catalyst behavior.
