The modern trends in design of chiral metallocene catalysts, well-defined living metathesis catalysts, catalysts tolerant toward functionalities and water systems are highlighted. The book discusses in detail the relevant aspects of these processes including reaction thermodynamics, kinetics, mechanisms and stereochemistry and correlates the structure of produced polymers with their chemical and physical-mechanical properties. Related important topics include Ziegler-Natta polymerization of olefins and dienes, atom transfer radical polymerization of vinyl compounds, metathesis of olefins and acetylenes, acyclic diene metathesis reaction, carbonyl olefination reaction, metathesis polymerization of acetylenes, metathesis degradation of polymers and ring-opening polymerization of heterocycles. Special emphasis is laid upon the manufacture of commerical products, new polymers and copolymers of potential interest for industry and design and synthesis of speciality polymers with particular structures and architectures and desired properties. The book critically evaluates the most recent achievements reported in this field and outlines the modern trends on the research and application of the catalytic processes for cycloolefin polymerization. For the first time, comprehensive information about the published data on the subject up to now is provided for both academic and industrial researchers working in the areas of polymer chemistry, organic and organometallic chemistry, surface science and catalysis, petrochemistry and chemical engineering.

This book was released on 2012-12-06 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Olefin metathesis reaction can be considered as one of the most successful organic reactions with many applications in the low molecular weight range and also in the polymer field. The use of catalysts with their selective and effective transformation properties in olefin metathesis I polymerization systems is a growing interest. There has been great effort and competition in developing active and commercially useful catalysts. The main aim of this ASI was to gather several research groups and also the people from industry. to present existing knowledge and latest results in the field. A wide range of topics through homogeneous and heterogeneous aspects have been considered. Attention has been drawn to the metal-carbene and metallacyclobutane complexes as active species, the initiation mechanisms, the stereochemistry and thermodynamics of these reactions. New catalytic systems for the metathesis of alkenes and alkynes and fot' ring opening polymeriZation I block copolymerization reactions have been introduced. Spectroscopic studies for the characteriZation of catalysts, simulation studies explaining the function of chain carrier species and polymer degradation have also been covered.

Available in PDF, EPUB and Kindle. Book excerpt: 45 years after the discovery of transition metals and organometallics as cocatalysts for the polymerization of olefins and for organic synthesis, these compounds have not lost their fascination. The birthday of Karl Ziegler, the great pioneer in this metalorganic catalysis, is now 100 years ago. Polyolefins and polydienes produced by Ziegler-Natta catalysis are the most important plastics and elastomers. New impulses for the polymerization of olefins have been brought about by highly active metallocenes and other single site catalysts. Just by changing the ligands of the organometallic compounds, the structure of the polymers produced can be tailored in a wide manner. In invited lectures and posters, relevant aspects of the metalorganic catalysts for synthesis and polymerization are discussed in this book. This includes mechanism and kinetics, stereochemistry, material properties, and industrial applications.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The development of new generation polymers is guided by Green Chemistry and sustainability. Biodegradable polymers derived from readily renewable resources, e.g., plants and carbon dioxide, are attractive as environmentally friendly alternatives to polymers derived from fossil fuels, and will play an increasing role in the market place. Polyoxygenates, such as polyesters and polycarbonates, are one important family of such polymers. In this work, the microstructure of poly(propylene carbonate) (PPC) has been studied by C-13 NMR spectroscopy. By analyzing polymer samples and model compounds, we observed tetrad and triad sensitivity for the carbonate and propylene carbon atoms, respectively. The reactions between (TPP)AlX, where TPP = tetraphenylporphyrin and X = Cl, O(CH2)9CH3 and O2C(CH2)6CH3, and propylene oxide, PO, have been studied and shown to give (TPP)AlOCHMeCH2X and (TPP)AlOCH2CHMeX compounds. The relative rates of ring opening of PO follow the order Cl> OR> O2CR, but in the presence of added 4-(dimethylamino)pyridine (DMAP) (1 equiv), the order is changed to O2CR> OR. From studies of kinetics, the ring opening of PO is shown to be first order in [Al]. Carbon dioxide inserts reversibly into the Al-OR bond to give the compound (TPP)AlO2COR, and this reaction is promoted by the addition of DMAP. On the basis of these results, the reaction pathway leading to ring opening of PO can be traced to an interchange associative mechanism, wherein coordination of PO to the electrophilic aluminum atom occurs within the vicinity of the Al-X bond. The gas-phase studies in an electrospray tandem mass spectrometer revealed that, for a series of related ions LM+, L = TPP or (R, R)- N, N'-bis(3,5-di-tert-butyl-salicylidene)-1,2-cyclohexenediamino) ((R, R)-salen), the Lewis acidity order follows M = Cr(III) %7E Al(III)> Co(III), and notable differences were observed when PO molecules coordinated to those metal centers. The preparations of LAlOCH2CH(S)MeCl, where L = (R, R) or (S, S)-salen, are reported together with the respective LAlOEt compounds, and their reactivities toward L- and rac-lactides in various solvents reveal the surprising complexity of the stereopreference for the ring-opening event.
