This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this thesis was to prepare thermoresponsive PEG-based homopolymers and copolymers by combination of cobalt-mediated catalytic chain-transfer polymerization (CCTP) and thiol-ene "click" chemistry and prepare well-defined glycopolymers via "living" polymerization and "click" chemistry. The effect of different catalysts for the nucleophilic mediated thiol-ene reaction was investigated using model compounds, both monomers and oligomers obtained by CCTP. Different catalysts, including pentylamine and hexylamine (primary amines), triethylamine (tertiary amine), and two different phosphines, dimethylphenylphosphine (DMPP) and tris(2-carboxyethyl) phosphine (TCEP), were investigated in the presence of different thiols. The optimum reaction conditions for nucleophile mediated thiol-ene click reactions were investigated. Thermoresponsive PEG-based homopolymers and copolymers of OEGMEMA obtained by CCT were modified using thiol-ene click chemistry with a variety of different functional thiol compounds to yield functional thermoresponsive polymers in high yield. The effect of different solvent systems for based catalyzed thiol-ene reaction was investigated in the presence of different functional thiols. The ATRP polymerization of TMS-PgMA and TIPS-PgMA and ROP polymerization of aliphatic polyester were investigated. A maleimide functional initiator was used in order to achieve post conjugation of nanoparticles for drug delivery. Moreover, the disulfide based bifunctional initiator was introduced into the midpoint of the polymer chain, which could break down to afford the corresponding polymer chain with thiol end group under the reducing condition. The thiol-terminated polymer was also post-functionalized via thiol-ene click chemistry. In addition, the aliphatic polycarbonate is a biocompatible and biodegradable polymer, which is widely used in medical and pharmaceutical applications. The subsequent introduction of sugar moiety to the reactive polymer chain via CuAAC click reaction and then the interactions between glycopolymers and lectins were investigated by Surface Plasmon Resonance (SPR) and Quartz Crystal Microbalance with Dissipation (QCM-D). The controlled SET-LRP polymerization of TMS-PgMA and SET-RAFT polymerization PgMA with the intact alkyne at ambient temperature were investigated. A maleimide functional initiator and CPDB, as the chain transfer agent have been employed. The introduction of maleimide moiety was to allow for post polymerization conjugation to peptides via reaction with cysteines. The subsequent introduction of sugar azides to click with the reactive polymer containing alkyne group and the glycopolymers through CuAAC was also investigated. The glycopolymer has been successfully prepared combining the SET-LRP/SET-RAFT and CuAAc click chemistry at ambient temperature.

Download or read book An Introduction to Polymer Colloids written by Françoise Candau and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest in the subject of Polymer Colloids over the last twenty five years or so has been very large resulting now in major international conferences on an annual basis and many national ones as well. The interest stems not only from the wide range of applications of these materials but also from a curiosity as to the mechanism of formation and their growing use as model particles to investigate fundamental aspects of physics and chemistry. In July 1988 a NATO Advanced Study Institute was held in Strasbourg, France, at the Centre St. Thomas. As an educational introduction to this I nstitute a series of eight lectures was given to cover the fundamental aspects of the subject. These eight lectures have now been compiled into an Introductory Text covering, emulsion poly merization, dispersion polymerization, inverse emulsion polymerization, the morphology of copolymer latices, the colloidal properties of latices, characterization methods and rheology. It is hoped that these will serve a wide audience, undergraduates, graduate-students and research workers, both in industry and academe. The chapters all contain review material up to date at the time of publication. fhe 1988 NATO Advanced Study I nstitute was made possible by a grant from the NATO-AS I programme and the following companies: BASF, Ludwigshafen, West Germany The Dow Chemical Company, Michigan, USA Dow Chemical Rheinwerk GmbH, Rheinmunster, West Germany ICI PLC, Runcorn, England S.

Download or read book Design Synthesis and Study of Functional Amphiphilic Polymers and Their Applications written by Huan He and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphiphilic homopolymers with high densities of functional groups are synthetically challenging. Thiol-yne nucleophilic click reactions have been investigated to introduce multiple functional groups in polymers with high density. An electron deficient alkyne group bearing methacrylate monomer was polymerized using reversible addition-fragmentation chain-transfer (RAFT) polymerization. Subsequently, the electron deficient alkyne group on polymer side chain was readily reacted with a thiol reagent using triethylamine (TEA) as the organocatalyst. This reaction was found to be very efficient under mild conditions. The resultant homopolymer bearing thiol vinyl ether functional groups could perform a second thiol addition with a stronger base, such as triazabicyclodecene(TBD), to prepare multifunctional homopolymers. This stepwise addition process was monitored by different techniques. The fidelity of this method was demonstrated by attaching four different functionalities, including both hydrophobic and hydrophilic moieties. Also, a novel polymerization method was developed using the same thiol-yne nucleophilic addition strategy. Typically, two bi-functional thiol-based monomers with activated alkyne termini differencing in their linker length can be prepared and polymerized utilizing this strategy. Under mild conditions, monomers can be polymerized conveniently to yield linear structures with high molecular weights. The polymerization conditions were optimized by screening various catalysts, solvents, temperatures, reaction time, and monomer concentrations. This new methodology efficiently yields polymers with high molecular weight. Moreover, the resulting polymer contains alkene backbone that acts as a functional handle for further modifications. For example, it can be subjected to a second thiol species to achieve multi-functional capabilities. These post-modified polymers with dithioacetal units in their backbone degrade in the presence of reactive oxygen species, providing the opportunity to design functional materials with stimuli-responsive features.
