521. Molecularly Dispersed Dendrimers in a Polymeric Matrix
Topic: Polymers
Published: 3/1/1999
Authors: Barry J. Bauer, T J. Prosa, D W. Liu, C L. Jackson, D A Tomalia, Eric J. Amis
Abstract: Interpenetrating polymer networks are formed by dissolving poly(amidoamine) dendrimers in 2-hydroxyethyl methacrylate and polymerizing with dendrimer contents between 1 and 25 mass % containing dendrimers from generation 6 through 11. Small angle x- ...

522. Comparison of Classical and MALDI-TOF-MS Analysis of a Polystyrene Interlaboratory Sample
Topic: Polymers
Published: 1/1/1999
Authors: William R. Blair, B M Fanconi, R J Goldschmidt, Charles Martin Guttman, William E Wallace III, S Wetzel, David Lloyd VanderHart
Abstract: Over the past several years, the use of MALDI-TOF-MS for analysis of synthetic polymers has increased significantly. As the number of polymer analyses by MALDI has increased, scrutiny of the MALDI results in comparison to classically derived values ...

523. Domain Structure and Interphase Dimensions in Poly(Urethaneurea) Elastomers Using DSC and SAXS
Topic: Polymers
Published: 1/1/1999
Authors: S G Musselman, T M Santosusso, J D. Barnes, L H Sperling
Abstract: Small-angle x-ray scattering (SAXS) and differential scattering calorimetry (DSC) were used to demonstrate distinct differences in domain size, phase separation, and hydrogen bonding in a series of segmented urethaneurea elastomers prepared from isoc ...

527. In-Line Dielectric Sensor for Chemical Composition Measurements in Molten Polymers
Topic: Polymers
Published: 1/1/1999
Authors: M M McBrearty, Anthony J. Bur, S Perusich
Abstract: We describe a dielectric sensor that incorporates a flow-through design so that it can be placed in-line on an extruder. Dielectric measurements have been successfully applied for measuring additive concentrations in polymer melts during extrusion p ...

528. In-Situ Monitoring of Product Shrinkage During Injection Molding Using an Optical Sensor
Topic: Polymers
Published: 1/1/1999
Authors: C L Thomas, Anthony J. Bur
Abstract: We have used an optical fiber sensor for in-situ monitoring of product shrinkage during injection molding. The sensor, consisting of a bundle of optical fibers with a sapphire window at its end, is positioned in the ejector pin channel of the mold s ...
