Since the pioneering advances of Karl Ziegler and Giulio Natta during the early 1950s, a
continuing series of breakthroughs in research and industrial innovations have greatly …

One of the most exciting developments in the areas of catalysis, organometallic chemistry,
and polymer science in recent years has been the intense exploration and …

The polyolefins production has increased rapidly in the 40 years to make polyolefins the
major tonnage plastics material worldwide. In 2003, 55 million tons of polyethene and 38 …

The outstandingly rapid scientific and technological development of metallocene-based
catalysts for olefin polymerization is a perfect example of the successful application of …

Staudinger predicted a correlation between the physical properties of a polymer and its main-
chain stereochemistry as early as 1929. 1 However it was not until 1947 that Schildknecht …

A relatively compact, but nonetheless comprehensive, review of the most important
preparative methods for the synthesis and chemical modification of polymers. The contents …

Metallocenes are very versatile catalysts for the production of polyolefins, polystyrene and
copolymers. Some polymers such as syndiotactic polypropene, syndiotactic polystyrene …

Ansa-metallocene complexes have been extensively studied as the precatalysts for olefin
polymerization. The bridges have important effects on the activities of the catalysts and …

The reactions of Cp* Zr (CH3) 3, 1, and Cp2Zr (CH3) 2, 2, with partially dehydroxylated
silica, silica− alumina, and alumina surfaces have been carried out with careful identification …
