Biological–synthetic hybrid block copolymers: Combining the best from two worldsWiley - Tập 43 Số 1 - Trang 1-17 - 2005
Harm‐Anton Klok
AbstractAlthough biopolymers and synthetic polymers share many common features, each of these two classes of materials is also characterized by a distinct and very specific set of advantages and disadvantages. Combining biopolymer elements with synthetic polymers into a single macromolecular conjugate is an interesting strategy for synergetically merging the proper...... hiện toàn bộ
Solvent‐free polymerization of citric acid and D‐sorbitolWiley - Tập 44 Số 14 - Trang 4259-4267 - 2006
Kenneth M. Doll, Randal L. Shogren, J. L. Willett, Graham Swift
AbstractCopolymers of citric acid and D‐sorbitol were synthesized with a solvent‐free vacuum‐oven synthesis with molar ratios of citric acid to D‐sorbitol ranging from 1/1 to 6/1. The extent of the reaction was followed by the monitoring of the residual acid content of the system. As expected, the reaction occurred much more ra...... hiện toàn bộ
Crosslinked polystyrene with improved mechanical propertiesWiley - Tập 31 Số 9 - Trang 2305-2311 - 1993

AbstractThe synthesis of some divinyl monomers—bis(vinylphenyl)ethane (2), bis(vinylbenzyloxy)hexane (3a), and bis(vinylbenzyloxy)dodecane (3b) is reported. Copolymers of the new monomers and styrene were evaluated as an alternative to divinylbenzene‐crosslinked polymers for use as matrices and ab...... hiện toàn bộ
Synthesis and characterization of perfluorinated arylenevinylene polymersWiley - Tập 48 Số 2 - Trang 285-291 - 2010

AbstractFully fluorinated arylenevinylene polymers have been synthesized via a methodology based on the Stille cross‐coupling reaction and characterized by FTIR spectroscopy and MALDI‐TOF mass spectrometry. Investigation of thin film properties by cyclic voltammetry and ellipsometry shows that complete substitution of hydrogen atoms with fluorine atoms on the conju...... hiện toàn bộ
Hydrolyzable poly(ester‐urethane) networks from L‐lysine diisocyanate and D,L‐lactide/ϵ‐caprolactone homo‐ and copolyester triolsWiley - Tập 32 Số 12 - Trang 2345-2363 - 1994
Robson F. Storey, Jeffrey S. Wiggins, A Puckett
AbstractBioabsorbable poly(ester‐urethane) networks were synthesized from ethyl 2,6‐diisocyanatohexanoate (L‐lysine diisocyanate) (LDI) and a series of polyester triols. LDI was synthesized by refluxing L‐lysine monohydrochloride with ethanol to form the ester, which was subsequently refluxed with 1,1,1,3,3,3‐hexamethyldisilazane to yield a silaz...... hiện toàn bộ
Novel polymer monolith prepared from a water‐soluble crosslinking agentWiley - Tập 45 Số 17 - Trang 3811-3817 - 2007
Takuya Kubo, Naomi Kimura, Ken Hosoya, Kunimitsu Kaya
AbstractIn this study, we described the fundamental properties of novel polymer monoliths that were prepared from a water‐soluble crosslinking agent. Each monolith was evaluated by scanning electron microscope (SEM) and scanning probe microscope (SPM) to observe the monolithic structure, and the polymer films that were prepared from several monomers were evaluated ...... hiện toàn bộ
Photoswitchable architectural polymer: Toward azo‐based polyamidoamine side‐chain dendritic polyesterWiley - Tập 39 Số 23 - Trang 4182-4188 - 2001
Samaresh Ghosh, A. K. Banthia
AbstractA versatile approach to the synthesis of novel polyamidoamine (PAMAM) side‐chain dendritic polyester (SCDPE) possessing azobenzene motifs in the polymeric core is described and displayed reversible cis–trans (E/Z) isomerization upon exposure to UV light. A polymerization reaction was conducted in solution using ester‐terminated PA...... hiện toàn bộ
