51. INVESTIGATION OF NANODISPERSION IN POLYSTYRENE -MONTMORILLONITE NANOCOMPOSITES BY SOLID STATE NMR
Published: 12/15/2003
Authors: S Bourbigot, Jeffrey W Gilman, David Lloyd VanderHart, W H. Awad, Rick D Davis, A B Morgan, C A Wilkie
Abstract: Nanocomposites result from combinations of materials with vastly different properties at the nanometer scale. These materials exhibit many unique properties, such as improved thermal stability, reduced flammability, and improved mechanical properties ...

52. High Throughput Methods for Polymer Nanocomposites Research: Extrusion, Nmr Characterization and Flammability Property Screening.
Published: 11/1/2003
Authors: Jeffrey W Gilman, S Bourbigot, John R Shields, Marc R. Nyden, Takashi Kashiwagi, Rick D Davis, David Lloyd VanderHart, W Demory, C A Wilkie, A B Morgan, J R Harris, R Lyon
Abstract: Several, recent, revolutionary advances in combinatorial (or high throughput, HT) polymer science have appeared in the literature, which significantly accelerate the rate of data generation. Although these new HT approaches may in part have been insp ...

53. Flame Retardant Mechanism of Silica - Effects of Molecular Weight of Resin
Published: 4/1/2003
Authors: Takashi Kashiwagi, John R Shields, Richard H. Harris Jr., Rick D Davis
Abstract: The effects of resin molecular weight, M^dw^, on the flame retardant mechanism of silica were studied using two different molecular weights of PMMA, 122,000 g/mol and 996,000 g/mol and two silicas, fused silica with a low surface area and silica gel ...

56. Processing Degradation of Polyamide 6/Montmorillonite Clay Nanocomposites and Clay Organic Modifier
Published: 1/1/2003
Authors: Rick D Davis, Jeffrey W Gilman, David Lloyd VanderHart
Abstract: Under injection molding conditions, typical of industrial processing, in situ polymerized montmorillonite/polyamide 6 nanocomposites significantly degraded, producing a four-fold increase in -caprolactam (monomer) content and a significant reduction ...
