Download or read book POLYMERIZATION AND CHARACTERIZATION OF METHYLMETHACRYLATE BY ATOM TRANSFER RADICAL POLYMERIZATION. written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, methylmethacrylate, MMA was polymerized by ATRP method to obtain low molecular weight living polymers. The initiator was p-toluenesulfonylchloride and catalyst ligand complex system were CuCl-4,4’ dimethyl 2,2’bipyridine. Polymers with controlled molecular weight were obtained. The polymer chains were shown by NMR investigation to be mostly syndiotactic. The molecular weight and molecular weight distribution of some polymer samples were measured by GPC method. The K and a constants in [h]=K Ma equation were measured as 9.13x10-5 and 0.74, respectively. FT-IR and X-Ray results showed regularity in polymer chains. The molecular weight-Tg relations were verified from results of molecular weight-DSC results.

Book Synopsis Atom Transfer Radical Polymerization by Continuous Feeding of Activators by : Mary Nguyen
Download or read book Atom Transfer Radical Polymerization by Continuous Feeding of Activators written by Mary Nguyen and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Atom transfer radical polymerizations (ATRP) of methyl acrylate (MA), methyl methacrylate (MMA) and styrene (St) were conducted by continuous feeding of Cu(I)X/Ligand activators. Typically, the monomer, the initiator, and a certain amount of deactivator, Cu(II)X2/Ligand, were placed in a Schlenk flask deoxygenized by bubbling with N2. The activator, Cu(I)X/Ligand, was placed in a gas-tight syringe and was added at a constant rate to the Schlenk flask using a syringe pump. In ATRP, the Cu(I) catalyst would undergo many oxidation/reduction cycles when the propagation of polymer chains is taking place. However, some of the Cu(I) would finally be oxidized to Cu(II) irreversibly. According to the principle of halogen conservation, the end-group loss equals the amount of Cu(I) that is permanently oxidized to Cu(II). Thus, by reducing the amount of Cu(I) added to the reaction, ATRP by continuous feeding of activators sets an upper limit of the potential end-group loss. The end-group fidelity information is readily known at the beginning of the reaction.
Book Synopsis Controlled Radical Polymerization with Dendrimers Containing Stable Radicals by :
Download or read book Controlled Radical Polymerization with Dendrimers Containing Stable Radicals written by and published by . This book was released on 1996 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: TEMPO-based stable radicals were attached to dendrimers of variable size and used to control radical polymerization of styrene, vinyl acetate and (meth)acrylates. Thermal polymerization of styrene with (G-2)-TEMPO proceeded in a similar but not better controlled manner than with TEMPO alone. In the polymerization of styrene initiated with BPO, the kinetics and the molecular weigh/conversion relations showed the same tendency as with TEMPO, though the polydispersity was higher than in the absence of dendrimers. This indicates that homolytic cleavage occurs at the reaction temperature, monomer can diffuse inside the cavity of dendrimer, and polymer is at least partially compatible with dendrimer. Model reactions indicate that the higher observed polydispersities could not be ascribed to transfer to benzyl hydrogen atoms. Therefore, the higher polydispersities could originate from the self-initiated polymerization of styrene outside of the dendrimers as well as the slow exchange of these chains with chains attached to dendrimers. To evaluate the effect of self-initiation, vinyl acetate, methyl methacrylate, and n-butyl acrylate were used, however, the resulting polymers were incompatible with the dendrimers. The growing chains are easily released from the cavity of the dendrimers into solution, and their return into the cavities of the dendrimers was not fast enough to control the polymerization. The results of the polymerization in decalin solution indicate that polymerization of these monomers is better controlled but only at the early stages of the polymerizations. The subsequent precipitation of polymers attached to the dendrimers prevent further polymerization.
Book Synopsis Miktoarm Star Polymers by : Ashok Kakkar
Download or read book Miktoarm Star Polymers written by Ashok Kakkar and published by Royal Society of Chemistry. This book was released on 2017-04-13 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term ‘miktoarm polymers’ refers to asymmetric branched macromolecules, a relatively new entry to the macromolecular field. Recent advances in their synthesis and intriguing supramolecular chemistry in a desired medium has seen a fast expansion of their applications. The composition of miktoarm polymers can be tailored and even pre-defined to allow a desired combination of functions, meaning polymer chemists can have complete control of the overall architecture of these macromolecules. By carefully selecting the composition, they can create supramolecular structures with intriguing properties, particularly for applications in biology. Miktoarm Star Polymers features chapters from experts actively working in this field, and provides the reader with a unique introduction to the fundamental principles of this exciting macromolecular system. Topics covered include the design, synthesis, characterization, self-assembly and applications of miktoarm polymers. The book is an excellent overview and up to date guide to those working in research in polymer chemistry, materials science, and polymers for medical applications.
Book Synopsis Controlled/Living Radical Polymerization by : Krzysztof Matyjaszewski
Download or read book Controlled/Living Radical Polymerization written by Krzysztof Matyjaszewski and published by OUP USA. This book was released on 2007-01-04 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preparation and characterization of new materials with precisely controlled macromolecular dimensions, functionalities, and decomposition, as well as with well-defined topologies, is perhaps the main focus of contemporary polymer synthesis. The best control of molecular functions can be achieved in a controlled/living polymerization -- a chain growth process without chain breaking reactions. Recently, controlled/living polymerizations have extended to radical systems which are not only commercially important, but also have the largest potential due to the availability of radically polymerizable monomers, facile copolymerization and undemanding experimental conditions. Controlled Radical Polymerization will examine recent advances in mechanistic and synthetic aspects of controlled/living radical (co)polymerization systems. Not only will this book be focused on recent progress in the dynamically developing field of controlled/living radical polymerization, but it will be a sequel to the very popular ACS Symposium Series 685, 768, and 854. The book will consist of >30 chapters separated into seven subsections: Fundamentals, Mechanism of ATRP, Mechanisms of SFRP and Degenerative Transfer Processes, Controlled Architecture by CRP, Organic-inorganic Hybrids by CRP, Biomaterials by CRP and Industrial Applications. This book targets chemists and polymer scientists in academia and in industry.
Book Synopsis Fundamentals of Polymerization by : Broja Mohan Mandal
Download or read book Fundamentals of Polymerization written by Broja Mohan Mandal and published by World Scientific. This book was released on 2013 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last twenty years, the field of the chemistry of polymerization witnessed enormous growth through the development of new concepts, catalysts, processes etc. Examples are: non classical living polymerizations (group transfer polymerization, living carbocationic polymerization, living radical polymerization and living ring-opening metathesis polymerization (ROMP)); new catalysts (metallocenes and late transition metal catalysts for stereospecific polymerization, Schrock and Grubbs catalyst for ROMP among others) and new processes such as miniemulsion, microemulsion polymerization and dispersion polymerization (in polar solvents). Apart from the developments in the chemistry of polymerization, methods have been developed for the evaluation of highly reliable rate constants of propagation in radical as well as cationic polymerization. All these have revolutionized the field of synthetic polymer chemistry. In the book, fundamentals of both the new and old polymerization chemistry have been dealt with. The new chemistry has been given nearly equal space along with the old.
