This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel PPO-based amphiphilic diblock copolymers and triphilic multiblock copolymer analogues of the architectures BA, CBA, CAB, and CABAC have been successfully synthesized by combination of atom transfer radical polymerization (ATRP) and copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) 'click' reaction. The A, B, and C components of the block copolymers comprise of hydrophilic poly(glycerol monomethacrylate) (PGMA), lipophilic poly(propylene oxide) (PPO), and perfluorocarbon segment, respectively. Molar mass values of the polymers were obtained from 1H and 19F NMR spectroscopy measurements. Size exclusion chromatography (SEC) analysis confirmed low polydispersities (1.2 ≤ Mw/Mn ≤ 1.5) of the polymers. The aggregation of the triphilic block copolymers analogues, CBA, CAB, and CABAC, in aqueous solution showed intriguing structures. The structures they formed were governed by the strong immiscibility between the lipophilic PPO blocks and the fluorophilic perfluorocarbon segments as well as the blocks sequence and length. Compartmentalized structures were observed due the strong immiscibility between the PPO block and the perfluorocarbon segment.

Available in PDF, EPUB and Kindle. Book excerpt: Continuing the tradition of its previous editions, the third edition of Introduction to Polymer Chemistry provides a well-rounded presentation of the principles and applications of natural, synthetic, inorganic, and organic polymers. With an emphasis on the environment and green chemistry and materials, this third edition offers detailed coverage of natural and synthetic giant molecules, inorganic and organic polymers, biomacromolecules, elastomers, adhesives, coatings, fibers, plastics, blends, caulks, composites, and ceramics. Using simple fundamentals, the book demonstrates how the basic principles of one polymer group can be applied to all of the other groups. It covers reactivities, synthesis and polymerization reactions, techniques for characterization and analysis, energy absorption and thermal conductivity, physical and optical properties, and practical applications. This edition addresses environmental concerns and green polymeric materials, including biodegradable polymers and microorganisms for synthesizing materials. Case studies woven within the text illustrate various developments and the societal and scientific contexts in which these changes occurred. Now including new material on environmental science, Introduction to Polymer Chemistry, Third Edition remains the premier book for understanding the behavior of polymers. Building on undergraduate work in foundational courses, the text fulfills the American Chemical Society Committee on Professional Training (ACS CPT) in-depth course requirement.

Available in PDF, EPUB and Kindle. Book excerpt: Due to its bioavailability and (bio)degradability, poly(lactide) (PLA) is an interesting polymer that is already being used as packaging material, surgical seam, and drug delivery system. Dependent on various parameters such as polymer composition, amphiphilicity, sample preparation, and the enantiomeric purity of lactide, PLA in an amphiphilic block copolymer can affect the self-assembly behavior dramatically. However, sizes and shapes of aggregates have a critical effect on the interactions between biological and drug delivery systems, where the general understanding of these polymers and their ability to influence self-assembly is of significant interest in science. The first part of this thesis describes the synthesis and study of a series of linear poly(L-lactide) (PLLA) and poly(D-lactide) (PDLA)-based amphiphilic block copolymers with varying PLA (hydrophobic), and poly(ethylene glycol) (PEG) (hydrophilic) chain lengths and different block copolymer sequences (PEG-PLA and PLA-PEG).

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of well-defined poly(ethylene oxide)-block-poly(octadecyl acrylate) (PEO-b-PODA) diblock copolymers were successfully synthesized by reversible addition fragmentation transfer (RAFT) polymerization with low polydispersities (M[subscript w]/M[subscript n] = 1.09-1.13). The crystallization behavior of poly(ethylene oxide)-block-poly(octadecyl acrylate) (PEO-b-PODA) diblock copolymers has been studied by differential scanning calorimetry (DSC), small-angle X-ray scattering (SAXS) and polarized optical microscopy (POM). The melt morphology of PEO455-PODA19 experienced a transition from lamella to cylinder at 130°C. For the double crystalline block copolymer PEO455-PODA19, the micro-phase separation at 55°C created lamellar micro-domains, which confined the PEO blocks as it crystallized. The leading crystallization of PEO blocks then created a space that confined PODA crystallites as they are developed. The spherulites were formed first when PEO started to crystallize, but crystallites with polyhedral shape finally formed. As for the micelle behavior, the transmission electron microscopy (TEM) showed that amphiphilic block copolymers PEO-PODA with different volume fractions of hydrophobic PODA blocks ranging from 21% to 54%, were able to self-assemble in water forming spherical micelles.
