Nematic phase behavior of combined main chain/side chain liquid crystal polymers
We investigate the isotropic-anisotropic phase transitions and the conformation of combinedmain-chain/side-chain liquid crystal polymers (MCSCLCPs) by numerically solving semiflexible chainself-consistent field theory (SCFT) equations with pseudo-spectral method. T...

UV-curable epoxy systems containing hyperbranched polymers: Kinetics investigation by photo-DSC
关键字:Epoxy resins,Photopolymerization,Photocalorimetry
The effect of the presence of a hyperbranched OH-functionalized polymer (HBP) on the kinetics of cationic photopolymerization of an epoxy system was investigated employing two complementary techniques, photo-DSC and real-time FT-IR spectroscopy....

MOBILE MAGNETIC RESONANCE: NONDESTRUCTIVE TESTING OF POLYMERS
关键字:MOBILE,MAGNETIC,RESONANCE,NONDESTRUCTIVE,TESTING,POLYMERS,
Magnetic Resonance (NMR: Nuclear Magnetic Resonance) is known in medical imaging as a diagnostic tool and in chemistry and as a spectroscopic method for molecular structural analysis. In both cases, the object of interest is ...

Characterization of Model Branched Polymers by Multi-Detector SEC in Good and Theta Solvents
关键字:Multi-Detector SEC
Size exclusion chromatography (SEC) has proven to be a valuable tool for characterization of polymers since its inception in the 1960’s[1].  Conventional SEC employs calibration with linear standards, most commonly narrow molecular we...

Nanogel Star Polymers as Interesting Soft Colloid Materials for Biomedical Applications: No Assembly Required
Polymers have numerous biomedical applications including delivery of therapeutic materials, imaging applications, tissue regeneration, antimicrobial action and others. We have developed a route to nanogel core star polymer amphiphiles with control over size, arm number, functionality, end groups and molecular architecture. Variants of these materials were originally developed to serve as sacri...

Hypercrosslinked Microporous Aromatic Heterocyclic Polymers for Highly Selective C02/N2 Separation
关键字: Gas adsorption, Heterocycle microporous polymer, Selectivity
     The global climate change caused by excessive carbon dioxide (C02) emissions has attracted widespread public concern in recent years. To stabilize atmospheric C02 levels and prevent global warming, it is imperative ...

Toughness and Brittle-ductile Transition of Particle Toughened Polymers
关键字: Particle toughened polymer, Toughness, Brittle-ductile transition
    The toughness and brittle-ductile transition of rigid and rubber particles toughened thermoplastic polymers were studied by theory and experiment. In theory, the toughness was analyzed by the energy dissipated by particle ...
