Copolymer

Three types of linear and planar-structured donor (D)–acceptor (A) type alternating copolymers were synthesized by incorporating intrachain noncovalent Coulomb interactions, based on 2,5-bisthieno[3,2-b]thiophene-1,4-bis(decyltetradecyloxy)benzene and benzothiadiazole (BT) moieties. The chain linearity and systematic adjustment of interchain organization was achieved by the incorporation of different number of electronegative fluorine atoms onto BT, which significantly affected the frontier energy

addition of graft copolymer and dynamic vulcanisation on the mechanical properties of these blends Recently, Baker et. al., [21] studied the effectiveness of various basic functional groups in polypropylene as compatibilisers in a PP/NBR system using morphological and impact property measurements. Commonly, it is simple to blend of similar polarities and solubility of rubber and plastic to make a valuable thermoplastic elastomer, for example PP/ethylene-propylene-diene copolymer EPDM, epoxidized

explained how, through synthesis it is possible to control the structure and properties of molecules to create functional materials. In order to obtain these functional materials, Dr. Grubbs and his research group have synthesized block and star-block copolymers, which depending on their properties can be used in different applications. To explain, polymers are commonly defined as macromolecules formed by repeat units called

ABSTRACT: Copolymers of aniline and o-phenylenediamine / kaolinite composites were synthesized by 5:1 molar ratios of the respective monomers with different percentages of nanoclay via modified in situ chemical co-polymerization. The results were verified by measuring the FT-IR and UV-vis absorption spectra for PANI-o-PDA / kaolinite composites. The thermal behaviour of the copolymer and composites was studied. PANI-o-PDA / kaolinite composites were thermally more stable than pure copolymer. Surface

Amphotericin B (AmB), a polyene macrolide antibiotic, is highly effective against various Leishmania species and is currently recommended as first line treatment for the visceral form (Dea-Ayuela et al., 2004). Amphoteric nature of AmB contributed by its hydrophobic (the polyene hydrocarbon chain) and hydrophilic (the polyhydroxyl chain) domains, is responsible for poor aqueous and organic solubility, and intercalation into cell membranes to elicit drug's pharmacological effects (Milhaud et al.,

biodegradable cationic PDMAEMA-PHB-PDMAEMA triblock copolymers were less toxic than PEI (25k) and PDMAEMA homopolymers and showed positive charge in aqueous solution that This provides the copolymer with a strong condensation ability with the negatively charged plasmid DNA (pDNA) to form copolymer/ pDNA polyplexes, which is an important process to prevent pDNA degradation by nucleases also PDMAEMA-PHB-PDMAEMA/DNA polyplexes

The miscibility of PVC and EVA is an example of a miscible blend of homopolymer-copolymer. This blend is made despite the immiscible behavior of the homopolymers. It as at certain ranges of copolymer composition that PVC is able to mix with EVA, while being not doing so with polyethylene and poly (vinyl acetate). It is possible that the two copolymer units’ repulsion forces influence the miscibility based on copolymer composition [1]. Studies show that EVA is able to mix with PVC with a vinyl acetate
