Available in PDF, EPUB and Kindle. Book excerpt: Advances in Polymer Science enjoys a longstanding tradition and good reputation in its community. Each volume is dedicated to a current topic, and each review critically surveys one aspect of that topic, to place it within the context of the volume. The volumes typically summarize the significant developments of the last 5 to 10 years and discuss them critically, presenting selected examples, explaining and illustrating the important principles, and bringing together many important references of primary literature. On that basis, future research directions in the area can be discussed. Advances in Polymer Science volumes thus are important references for every polymer scientist, as well as for other scientists interested in polymer science - as an introduction to a neighboring field, or as a compilation of detailed information for the specialist.

Download or read book Synthesis and Solution Properties of Water soluble Fullerene Polymeric Systems written by Zhaoling Yao and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Water-soluble fullerene containing polymers comprising of poly(2-(dimethylamino) ethyl methacrylate)-fullerene (PDMAEMA-C60) with targeting moieties, poly(oligo(ethylene glycol) methyl ether methacrylate)-C60 (POEGMA-C60), nanocrystalline cellulose-fullerene (NCC-C60) and NCC-C60-POEGMA were synthesized and their solution properties were investigated. PDMAEMA-C60 with galactose targeting moiety was prepared by atom transfer radical polymerization (ATRP) and atom transfer radical addition (ATRA) processes. The self-assembly of galactose functionalized PDMAEMA-C60 structure in aqueous solutions was investigated using dynamic light scattering (DLS) at different pHs. A smaller hydrodynamic radius (Rh) was observed at pH 10 than at pH 3 due to electrostatic repulsion at low pH values. In addition, free PDMAEMA chains induced the demicellization of self-assembled nanostructures caused by the formation of charge transfer complex between PDMAEMA and C60. A well-defined poly(di(ethylene glycol) methyl ether methacrylate-stat-oligo(ethylene glycol) methyl ether methacrylate)-block-poly(di(ethylene glycol) methyl ether methacrylate ((PMEO2MA-stat-POEGMA300)-b-PMEO2) was successfully synthesized at room temperature via a two-step ATRP process. The block copolymer exhibited two thermal transitions at ~ 30 and 45 oC, which was believed to be associated with the formation of micelles and larger aggregates. The Rh of the aggregates increased from 47 to 90 nm, the aggregation number increased from 76 to ~9800 and Rg/Rh increased from 0.75 to 1.2 within the temperature range of 34 to 45oC. Well-defined statistical (PMEO2MA-stat-POEGMA300)-C60 was synthesized via ATRP and ATRA. The lower critical solution temperature (LCST) of (PMEO2MA-stat-POEGMA300)-C60 increased with methanol content in water, exhibiting lower LCSTs than PMEO2MA-stat-POEGMA300 for all methanol/water compositions. Higher critical micelle concentration (CMC) and larger spherical micelles were observed for (PMEO2MA-stat-POEGMA300)-C60 with increasing methanol content. The Rh of the micelles remained constant at temperature below the LCST and increased dramatically at temperature greater than the LCST, and (Rg/Rh) increased from ~ 0.75 to ~ 1.0. Nanocrystalline cellulose (NCC) was modified with water-soluble C60-([beta]-cyclodextrin) and (PMEO2MA-stat-POEGMA300)-C60) through a radical coupling reaction. NCC-C60-(PMEO2MA-stat-POEGMA300) possessed thermal responsive behavior in water and ~3.5 oC hysteresis associated with the heating/cooling cycles. No observable damage to NCC occurred during the radical coupling reaction as determined by TEM. NCC-C60-([beta]-cyclodextrin) possessed a similar thermal degradation behavior as NCC except it possessed a broader temperature range. Both NCC-fullerene systems demonstrated a radical scavenging activity when screened with the 2,2-diphenyl-1-picrylhydrazyl (DPPH). In addition, the drug loading and delivery using PDMAEMA-C60 with targeting moieties was explored. Two model drugs, namely fluorescein and pyrene were employed to evaluate the location of drug in the self-assembled structure of PDMAEMA-C60. It was found that the hydrophobic drugs were partitioned between the PDMAEMA shells and the hydrophobic fullerene cores. The drug delivery profiles indicated that PDMAEMA-C60 is an efficient drug carrier, however, it was cytotoxic to cells. The gene transfection efficacy of PDMAEMA-C60 to different cell lines was investigated and the results demonstrated that PDMAEMA-C60 exhibited good gene transfection performance. However, the targeting selectivity to liver cells cannot be determined in both cases. This study demonstrates that nanostructures of stimuli-responsive fullerene polymers can be controlled and manipulated by changing the external environments. Several potential applications, such as in drug and gene delivery, and free radical scavenging can be further explored.

Download or read book Atom Transfer Radical Polymerization written by Tharanikkarasu Kannan and published by LAP Lambert Academic Publishing. This book was released on 2010-05 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional radical polymerization is widely used in industries due to its simple polymerization conditions. But, molecular weight of polymers are difficult to control in this method. To achieve control over molecular weight and molecular weight distribution, many controlled radical polymerization methods have been proposed such as INIFERTER, NMP, RAFT and ATRP. In the field of ATRP, due to its simplicity and versatility, more than 7000 research articles have been published in the reputed journals during the last 15 years. But polyurethane-based tri-block copolymers have not been reported so far through ATRP and hence this book concentrates on novel routes to synthesize these tri-block copolymers via ATRP. Four different types of polyurethane macroinitiators for ATRP have been synthesized and used for the polymerization of vinyl and acrylate monomers. Results show that the present macroinitiators polymerize monomers through ATRP mechanism. These macroinitiators are highly potential to polymerize wide variety of monomers and resulting block copolymers would be very useful for academic as well as industrial research.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis outlines the first synthesis of a new complex branched polymer architecture that aims to combine the benefits of dendrimers with the simplicity of conventional polymerisation. There is no other available literature on these remarkable materials, dubbed hyperbranched polydendrons, due to their novelty. The new materials were shown to have very high molecular weights (>1,000,000 g/mol), exceptional self-assembly and encapsulation behaviour and unparalleled functionalisation capabilities, and were studied pharmacologically to determine their potential as oral nanomedicine candidates. The detailed investigation of the chemical variables involved in synthesising hyperbranched polydendrons has shown that their self-assembly and pharmacological behaviour can be turned on and off and fine-tuned by altering the composition of the materials. The permeation of the self-assembled particles through model gut epithelium suggests the potential for oral dosing of drug loaded nanomedicines that result in circulating nanoparticles – a research goal that is currently being pursued by several groups around the globe.
