This book was released on 2012-12-06 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the last ASI in Turkey in Sept. 1995, the olefin metathesis has made remarkable strong developments with an incredible speed in various directions. New catalyst systems have been developed which have resulted in the synthesis of novel materials. Other fascinating developments have been the new catalysts for stereoselective metathesis and catalysts with considerable functional group tolerance. These new catalysts in addition to Ring Opening Metathesis Polymerisation (ROMP) and Acyclic Diene Metathesis (ADMET) are now powerful tools for Ring Closing Metathesis (RCM) and have found many applications in the synthesis of natural products. A lot of information has been established about all aspects of the olefin metathesis and there is a vast literature concerning the process, covering the initiators, mechanistic features and applications of this reaction in organic and polymer synthesis. The NATO ASI on rd th ROMP and Related Chemistry took place in Polanica-Zdroj, Poland during 3 to 15 Sept. 2000, to highlight the developments in this area and to discuss the prospects and visions for the year 2000 and beyond. The aims of the ASI were: to provide a platform for dissemination of knowledge; to promote communication between people who have a serious interest in this field of chemistry; to help establishing international scientific contacts and to provide an opportunity for the scientists with an appropriate scientific background to learn of recent developments in this field of science. There were 15 lecturers and 67 participants in this NATO ASI.

Book excerpt: In recent years, the olefins metathesis has established itself as a powerful tool for carbon-carbon bonds forming and has found numerous applications in polymer chemistry. One of the important directions of metathesis is the polymerization with cycle opening. A study of new ruthenium catalysts, resistant to the many functional groups effects, has showed the possibility of synthesizing functionalized polymers with unique properties. In this chapter, reactivity and activation parameters of eight different norbornene dicarboxylic acid alkyl esters in the presence of a Hoveyda-Grubbs II catalyst for the ring opening metathesis polymerization were determined by 1H NMR analysis in-situ. The molecules of esters differ in the aliphatic radical structure and the location of the substituent groups. Kinetic studies have shown that effective polymerization constants and activation parameters strongly depend on the monomer structure. It is shown that the elongation of the aliphatic radical does not significantly affect the reactivity, but significantly changes the activation parameters. The branching of the aliphatic radical significantly affects both the reactivity of the corresponding ester and the activation parameters of the polymerization. The position of the substituents in the norbornene ring of the ester also has a significant effect on the activation parameters of metathesis polymerization.

Available in PDF, EPUB and Kindle. Book excerpt: A handbook on syntheses and properties, production processes, and applications of maleic anhydride and maleic anhydride derived products – all in one text. This handbook provides a comprehensive overview of maleic anhydride chemistry and applications from the professional perspective. With chapters written by leading R&D scientists from the chemical industry, and edited by the Vice President and ASI Technology Chief at Ashland Specialty Ingredients (ASI), Dr. Osama M. Musa, readers will find a unique perspective and summary of the latest advancements in the field of maleic anhydride science. Maleic anhydride is produced industrially on large scale (10E3 kt/annum). Its rich chemistry makes it an important raw material for numerous products and processes (e.g. for applications in polymers and coatings), many of which are covered in this handbook for the first time in a comprehensive manner. The broad scope spans topics ranging from production techniques (including topics such as processes, catalysis, trouble-shooting), synthesis and properties of small and polymeric maleic anhydride based compounds (focusing on industrially relevant compounds as well as emerging areas of importance) and in-depth and broad discussions of commercial maleic anhydride based applications.

This book was released on 2012-12-06 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first NATO Advanced Study Institute on Olefin Metathesis and Polymerization Catalysts was held on September 10-22, 1989 in Akcay, Turkey. Based on the fundamental research of RRSchrock, RGrubbs and K.B.Wagener in the field of ring opening metathesis polymerization (ROMP), acyclic diene metathesis (ADMET) and alkyne polymerization, these areas gained growing interest within the last years. Therefore the second NATO-ASI held on metathesis reactions was on Ring Opening Metathesis Po lymerization of Olefins and Polymerization of Alkynes on September 3-16, 1995 in Akcay, Turkey. The course joined inorganic, organic and polymer chemists to exchange their knowledge in this field. This volume contains the main and short lectures held in Akcay. To include ADMET reactions better into the title of this volume we changed it into: Metathesis Polymerization of Olefins and Alkyne Polymerization. This volume is addressed to research scientists, but also to those who start to work in the area of olefin metathesis and alkyne polymerization. The topics of the course were: mechanism of ROMP reactions/ new catalysts for ROMP/ new products by ROMP/ new catalysts for ADMET/ new products by ADMETI degradation of polymer by metathesis reactions/ alkyne polymerization and metathesis/ industrial application of metathesis reactions. The Advanced Study Institute was generously sponsored by the Scientific Affairs Division of NATO and the editor gratefully acknowledges this sponsorship. We also thank the Members of the Local Organizing Committee for their engagement on a successful NATO-AS!.

Download or read book Synthesis and Ring opening Metathesis Polymerization of Norbornenes Containing Pendent Aromatic and Aliphatic Side Chains written by and published by . This book was released on 1908 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of well-defined polynorbornenes containing pendent aromatic ether or aliphatic side chains have been prepared. Synthesis of the monomeric materials proceeded via initial cyclopentadienyl iron-mediated nucleophilic aromatic substitution reactions and DCC-mediated condensation reactions, followed by removal of the metal moiety via photolytic demetallation. Structural analysis of both the metallated and nonmetallated compounds was accomplished using homo- and heteronuclear correlation spectroscopic techniques as well as IR, MS and C, H elemental analysis. Subsequent ring-opening metathesis polymerization of these building blocks was achieved in the presence of a ruthenium-based catalyst, namely bis(tricyclohexylphosphine)benzylidene ruthenium (IV) dichloride, which liberated the resulting polymeric materials in high conversion of the monomer to the polymer. Gel permeation chromatography of each of the polymers revealed high molecular weights as well as low to narrow polydispersity indices. Thermal analysis of the aromatic ether functionalized polynorbornenes was accomplished using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). These results showed that when the number of aromatic groups pendent to the polymer chain increased (within each polymer repeat unit), a subsequent increase in the thermal stability was noted. TGA of the aliphatic-bridged systems revealed decreased thermal stability as the length of the aliphatic flexible spacer increased. Changing the spacer from a purely methylene-bridged system to one containing a tri(ethylene glycol) chain was found to increase the overall thermal properties of the resulting polymeric material.
