catalyst for the 1,4-cis-polymerization (>99%) of 1,3-butadiene. To our knowledge, this stereoselectivity is the highest reported for 1,3-butadiene polymerization with a heterogeneous catalyst. We further present evidence for the single-site structure of 1 as well as File Size: 2MB. This finding marked the first discovery of a stereoselective catalyst for epoxide polymerization. Since that time, significant advances have been made in stereoselective epoxide polymerization.
Purchase Alkene Polymerization Reactions with Transition Metal Catalysts, Volume - 1st Edition. Print Book & E-Book. ISBN , More than 30 years after the discovery of transition metals and organometal lics as catalysts for olefin polymerization these catalysts did not have lost their fascination. Since when Karl Ziegler has discovered the catalytic polymerization of ethylene leading to plastically formable polymers.
Since then, many research groups have explored the field of stereoselective polymerization of lactide, and many single-site metal catalyst-initiators have been developed and exploited to produce stereoregular PLA s. Three metal catalyst-initiator systems have been demonstrated to exhibit unique stereocontrol in lactide polymerization.

Box, AE, Enschede, The by: Stereoselectivity proceeds through either polymer chain control or catalyst site control, depending primarily on the symmetry (C 2n, C 2, meso‐C S, C S, or C 1) of the initiator, but also on temperature, solvent and monomer.
The kinetics and other characteristics of stereoselective polymerization are described with emphasis on the parameters. Since the discovery of metallocene catalysts, much effort has been paid to develop new organometallic compounds for polymerization catalysis, so-called single-site catalysts [1, 2].
The active spices of group 4 single-site catalyst is an ion pair composed of a cationic metal center and a counter anion which are derived from an organometallic. CRC/Taylor & Francis, Boca Raton pp., hardcover $ —ISBN ‐1‐‐‐4 Although I winced at the title (many of the catalysts described are two‐site catalysts rather than single‐site, as pointed out in several chapters), the book is a good reference text covering all important aspects of stereoselective polymerization, not only of the classic olefins and.
