513. The Influence of Electrospray Deposition in Matrix-assisted Laser Desorption/Ionization Mass Spectrometry Sample Preparation for Synthetic Polymers
Topic: Polymers
Published: 5/1/2004
Authors: S Wetzel, Charles Martin Guttman, Kathleen M. Flynn
Abstract: Three polymers of differing thermal stability, polystyrene (PS), polyethylene glycol (PEG), and polypropylene glycol (PPG) were studied by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) as the electro-spray deposition voltag ...

514. The Influence of Laser Energy of MALDI on the Molecular Mass Distribution of Synthetic Polymers
Topic: Polymers
Published: 5/1/2001
Authors: S Wetzel, Charles Martin Guttman, Kathleen M. Flynn
Abstract: The desorption/ionization process of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) is not completely understood. Characterization of synthetic polymers by MALDI-TOF-MS is very sensitive to the instrument ...

515. The Influence of Molecular Architecture and Solvent Type on the Size and Structure of Poly (Bezyl Ether) Dendrimers by SANS
Topic: Polymers
Published: 4/1/2001
Authors: G Evmenenko, Barry J. Bauer, R Kleppinger, B Forier, W Dehaen, Eric J. Amis, N Mischenko, H Reynaers
Abstract: The size of poly(benzyl ether) dendrimers with different molecular architectures was measured by small angle neutron scattering (SANS). Both polar and non-polar solvents were used to measure the effect of solvent type. The radius of gyration (Rg) o ...

517. The Influence of Shearing Parameters on the Frictional Forces Measured Between Polymer Brushes
Topic: Polymers
Published: 1/1/2003
Authors: Aaron M Forster, S. Michael Kilbey
Abstract: Polymer brushes have potential as end-tethered lubricants. Brush layers immersed in a good solvent must be compressed to ~16% of their equilibrium height before friction forces are measured. The same experiment in a solvent near the theta temperatu ...

518. The Influence of the Laser Energy and Matrix of MALDI on the Molecular Mass Distribution of Poly(ethylene glycol)
Topic: Polymers
Published: 3/1/2003
Authors: S Wetzel, Charles Martin Guttman, Kathleen M. Flynn
Abstract: The molecular mass distribution (MMD) that is obtained in synthetic polymer characterization may be biased by preferential desorption/ionization of low mass polymer molecules, preferential ion attachment to larger polymers, or degradation and fragmen ...
