Download or read book Monitoring Polymerization Reactions written by Wayne F. Reed and published by John Wiley & Sons. This book was released on 2014-01-21 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offers new strategies to optimize polymer reactions With contributions from leading macromolecular scientists and engineers, this book provides a practical guide to polymerization monitoring. It enables laboratory researchers to optimize polymer reactions by providing them with a better understanding of the underlying reaction kinetics and mechanisms. Moreover, it opens the door to improved industrial-scale reactions, including enhanced product quality and reduced harmful emissions. Monitoring Polymerization Reactions begins with a review of the basic elements of polymer reactions and their kinetics, including an overview of stimuli-responsive polymers. Next, it explains why certain polymer and reaction characteristics need to be monitored. The book then explores a variety of practical topics, including: Principles and applications of important polymer characterization tools, such as light scattering, gel permeation chromatography, calorimetry, rheology, and spectroscopy Automatic continuous online monitoring of polymerization (ACOMP) reactions, a flexible platform that enables characterization tools to be employed simultaneously during reactions in order to obtain a complete record of multiple reaction features Modeling of polymerization reactions and numerical approaches Applications that optimize the manufacture of industrially important polymers Throughout the book, the authors provide step-by-step strategies for implementation. In addition, ample use of case studies helps readers understand the benefits of various monitoring strategies and approaches, enabling them to choose the best one to match their needs. As new stimuli-responsive and "intelligent" polymers continue to be developed, the ability to monitor reactions will become increasingly important. With this book as their guide, polymer scientists and engineers can take full advantage of the latest monitoring strategies to optimize reactions in both the lab and the manufacturing plant.
Download or read book Functional Polymers by Post Polymerization Modification written by Patrick Theato and published by John Wiley & Sons. This book was released on 2013-02-12 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: In modern polymer science a variety of polymerization methods for the direct synthesis of polymers bearing functional groups are known. However, there is still a large number of functional groups that may either completely prevent polymerization or lead to side reactions. Post-polymerization modification, also known as polymer-analogous modification, is an alternative approach to overcome these limitations. It is based on the polymerization of monomers with functional groups that are inert towards the polymerization conditions but allow a quantitative conversion in a subsequent reaction step yielding a broad range of other functional groups. Thus, diverse libraries of functional polymers with identical average degrees of polymerization but variable side chain functionality may easily be generated. Filling the gap for a book dealing with synthetic strategies and recent developments, this volume provides a comprehensive and up-to-date overview of the field of post-polymerization modification. As such, the international team of expert authors covers a wide range of topics, including new synthetic techniques utilizing different reactive groups for post-polymerization modifications with examples ranging from modification of biomimetic and biological polymers to modification of surfaces. With its guidelines this is an indispensable and interdisciplinary reference for scientists working in both academic and industrial polymer research.

Download or read book Design and Synthesis of Monomers Toward Sequence Controlled Polymers written by Margaret Gerthoffer and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strategies to synthesize sequence-defined polymers remain limited for industrial-scale applications, often due to time consuming iterative addition or polymerization methods possessing low functional group tolerances. Throughout my PhD, I have utilized both ring-opening metathesis polymerization (ROMP) and pressure-induced polymerization to form sequence-defined polymers from deliberately designed A-B monomers. ROMP of electronically-biased paracyclophanedienes (pCpd) can form donor-acceptor poly(arylenevinylene)s. In addition, the pressure-induced polymerization of engineered aryl/perfluoroaryl (Ar/ArF) co-crystals translates into sequence-specific sp3-saturated copolymers known as nanothreads. Both polymerization methods form sequence-specific copolymers as dictated by the supramolecular monomer design. The ROMP of ring-strained pCpds containing dialkyloxybenzene donor and benzothiadiazole acceptor obtains well-defined polymers with ruthenium-based initiators. This design promotes favors sequence specificity between the electronically-activated dialkyloxybenzene and electronically-deficient benzothiadiazole that can guide the initiator homogenously during ring opening and polymerization events. During my PhD, I have discovered that the presence of sterically asymmetric alkyloxy groups (methoxy and octyloxy) on the donor further guides the polymerization process. I have elucidated that the steric effects of the alkyloxy donor group can further control the rate of well-defined donor-acceptor copolymer synthesis due to supramolecular interactions with ruthenium-based initiators. To expand on this, I targeted the synthesis of various alkyloxybenzene donor groups in both linear and branched substitutions to compare ROMP rate and polymer sequence definition with benzothiadiazole acceptors. The investigated pCpds formed well-defined polymers that did not prohibit ruthenium-catalyst attachment as confirmed by GPC and NMR spectroscopy. I have moreover been able to synthesize ladderane-like polymers known as nanothreads by the pressure-induced polymerization (23+ GPa) of alternating eclipsed stacks of aromatic cores in solid-state Ar/ArF co-crystals. I have designed monomer pairs through preorganization of Ar/ArF synthons with varied quadrupole, hydrogen, and halogen bonding to understand the design elements necessary to form substituted nanothreads at reduced pressure thresholds. For all co-crystals, supramolecular engineering has reduced polymerization pressures compared to individual components as confirmed through in situ Raman, NMR, and XRD spectroscopies under pressure. Phenol:pentafluorophenol illustrates strong hydrogen bonding that stabilizes interstack interactions under pressure to form nanothreads. However, I discovered that hydrogen bonding amongst external functionalities can prohibit facile compressibility if the direction aligns to the putative Ar/ArF thread axis. Direct intrastack hydrogen bonding can in fact increase the required pressure of polymerization (30 GPa+). Designing appropriate hydrogen bonding scaffolds in Ar/ArF co-crystals thus offers the ability to target sequence-controlled nanothread production at a reduced pressure.

Download or read book Template Polymerization written by Stefan Polowinski and published by ChemTec Publishing. This book was released on 1997 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Template polymerization is a new field in polymer synthesis but common practice in the biosynthesis since DNA is the most popular template or matrix on which proteins are built by living species. This field is relevant to the synthesis of polymers of controlled structure but its application goes beyond the synthesis. Materials are formulated in complex mixtures always containing components which can be regarded as templates on which other materials are formed, modified, or are interacted with. In the new product development the relevance of these phenomena is controlled by the order of addition which affects probabilities and preferences of interaction. The current publication outlines mechanisms of template polymerization, polycondensation, and copolymerization. These mechanisms, illustrated with numerous examples, indicate a range of possibilities which can be encountered in materials and utilized to modify their properties. Orientation of substrates on template and their effect on modification of their reactivity and properties such as, for example, absorption of light or water are also discussed. Several chapters contain information on these studies discussed with sufficient detail to give reader comprehensive understanding of the methods used in various research laboratories and their findings."--Publisher's description.
