CHAIN END-GROUP ANALYSIS OF ETHENE HOMO- AND COPOLYMERS PREPARED WITH METALLOCENE CATALYSTS AT HIGH TEMPERATURE

No full textThe second half of the last Century is often referred to as 'the Age of Plastics'. Whether this calls to one's mind the 1963 Nobel Laureates Karl Ziegler and Giulio Natta, or "The Graduate" Ben Braddock of Charles Webb's novel (played by Dustin Hoffman in a 1967 cult movie) being explained that "the future is in plastics", the conclusion can only be that there is indeed some truth in the definition. But that is over now, and the new Millennium has much more and better to offer than 'plastics'-or not? This perspective article will not address such an epochal question; more modestly, it will make the point that-at odds with a growing misconception-there is still room for good and useful research in metal-catalysed olefin polymerisation for quite some years to come
Catalytic olefin polymerization is a mature field. Isn'it?
No full textIn 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
