Catalytic olefin polymerization is a mature field. Isn'it?

In spite of the reputation to be a mature area, Ziegler-Natta olefin polymerization continues to produce scientific and industrial breakthroughs at a surprising pace. The massive introduction of High Throughput Screening technologies has accelerated the innovation processeven further This Highlight aims at introducing the reader to a number of very recent publications in which novel metallocene and non-metallocene ("postmetallocene") olefin polymerization catalysts, and new concepts of chain growth in insertion polymerization, are disclosed and elegantly and convincingly discussed.
