Available in PDF, EPUB and Kindle. Book excerpt: Renowned experts give all essential aspects of the techniques and applications of graft copolymers based on polysaccharides. Polysaccharides are the most abundant natural organic materials and polysaccharide based graft copolymers are of great importance and widely used in various fields. Natural polysaccharides have recently received more attention due to their advantages over synthetic polymers by being non-toxic, biodegradable and available at low cost. Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.

This book was released on 2008 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: A range of strategies exist for the production of polyolefin block copolymers with well-defined morphologies for the compatibilization of immiscible blends; however, high sensitivity to impurities and use of expensive transition-metal catalysts limit their economic viability. An alternative method is the solvent-free coupling of dislike polymers using peroxides and multifunctional coagents. This technique, however, does not distinguish between a blend of gelled homopolymers and the intended copolymer. The use of a solution-based approach, like the one described in this report, for the radical-mediated coupling of polyolefins with dislike polymers allows for the full characterization of the copolymer without the formation of gel. A one- and two-step synthesis for the coupling of two homopolymers in solution is demonstrated using triallyl trimesate. The one-step approach produced a copolymer in low yields due to the differences in reactivity between the homopolymers. The two-step synthesis consisted of the solvent-free grafting of the coagent to the less reactive polymer, followed by coupling in solution with the other polymer. Though this technique demonstrated improved yields over that of the one-step approach, the overall yields were limited due to the dilution effects of the high solvent levels needed for comiscibility. The coupling of polyethylene with poly(ethylene oxide) had a maximum graft yield of 9.5%, whereas the coupling between polypropylene and a thermoplastic polyolefin elastomer was negligible. It was found that the grafting of allylic ester coagents to polyethylene results in an uneven graft distribution. Given enough peroxide and coagent, the material will reach its gel point where there is a small, high molecular weight population with a disproportionately high graft content, while the remaining chains contained a modest concentration of bound coagent. Furthermore, a survey of the effectiveness of several common coagents in the radical-mediated crosslinking of polyethylene was investigated where it was found that allylic coagents had a greater contribution to the crosslink density of the resin than vinyl coagents.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Naturally produced peptides or proteins can be regarded as highly refined polymers. When synthetic polymers are married to proteins or peptides, the resulting bioconjugates can synergistically combine the properties of the individual components and overcome their separate limitations. This Thesis is focused on the study of hybrid copolymers based on polypeptides and polymacrolactones. Block and graft copolymers have been synthesized by making use of the ring opening polymerization method (ROP) mainly and extensively characterized including both their chemical structure and their structure in the solid state. The self-assembly properties of the new copolymers have been preliminary examined regarding their potential application as nanocarriers for pharmaceutical compounds. This Thesis initially reports the ROP of w-pentadecalactone (PDL) using different amino-ended initiators and assisted by either organic or enzymatic catalysts. This method was then extended for the ROP of PDL using bisamino-ended poly(ethylene glycol) (PEG) for the preparation of poly(w-pentadecalactone)-b-poly(ethylene glycol)-b-poly(wpentadecalactone) [PPDLx-PEG-PPDLx] triblock copolymers. These amphiphilic ABA-type copolymers were able to selfassemble in water to form nanoparticles with diameters between 100 and 200 nm. Hybrid copolymers of poly(ester-peptide) or poly(ether-ester-peptide) type exhibiting different architectures (e.g. diblock, triblock, graft or triblock/grafted) respectively, were then synthesized using as building blocks: poly(w-pentadecalactone), poly(globalide) (PGl), PEG as well as polypeptides derived from the L-glutamic acid (Glu), L-lysine (Lys), L-alanine (Ala) and L-phenylalanine (Phe) a-amino acids. The hybrid copolymers were synthesized through several stages depending on the desired architecture. The first stage in the preparation of these copolymers was the synthesis of macroinitiators from PDL or PGl containing either an amino group at the end of the chain or multiple amine groups along their polymeric chain. In the second stage, such macroinitiators were used to trigger the polymerization of the a-amino acid N-carboxyanhyrides (NCA) with the COOH group of L-glutamic acid and NH2 of L-lysine duly protected as g-benzyl-L-glutamate (BLG) and eNcarbobenzoxy-L-lysine (ZLL) respectively. Some copolymers containing BLG or ZLL units were treated with acids to render copolymers bearing the amino acids residues with their COOH or NH2 functionalities in the free form. All of the synthesized copolymers were fully characterized through GPC and NMR spectroscopy. The thermal properties were studied by TGA and DSC techniques. The conformation adopted by the peptide-based copolymers in the solid-state was assessed by FTIR, and their crystalline structure was examined by X-ray diffraction using synchrotron radiation in most cases. The conformation in aqueous solution of water-soluble copolymers containing Glu or Lys residues in the free form was explored by circular dichroism. The self-assembly behavior in aqueous medium of all the amphiphilic copolymers was investigated with the purpose of obtaining nanoparticles with the appropriated diameters required for their application as biomedical nanocarriers. The nanoparticles were duly characterized by light scattering and SEM and TEM microscopies. Block and graft copolymers were able to load doxorubicin and release it under pH control. Copolymers containing L-lysine were shown to be able of condensing DNA. The potential of these copolymers as 31S of anticancer drugs and vectors for transfection have been evidenced.
