Blends of Fatty-Acid-Modified Dendrimers With Polyolefins

January 1, 2000
Author(s)
Barry J. Bauer, A Ramzi, D W. Liu, R L. Scherrenberg, P Froehling, J Joosten
Blends were made by solution and melt mixing fatty acid modified dendrimers with various polyolefins. Small angle neutron scattering (SANS) was used to determine the miscibility of the blends. Poly propylene imine (PPI) dendrimers G1, G3, and G5 (DAB-dendr

Real-Time Dielectric Measurements During Extrusion of Filled Polymers

January 1, 2000

M M. McBrearty, Anthony J. Bur, S C. Roth
Mineral fillers are added to extend and modify physical properties of polymers. To achieve porcessing control of mixing, real-time measurements are needed. Previuos work has shown that dielectric sensors can measure concentrations of fillers in non-polar

The Effect of Processing on Interfacial Shear Properties of Composite Materials

Walter G. McDonough, Joy P. Dunkers, Gale A. Holmes, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The objective of our research was to extend the use of the single fiber fragmentation test to include fast reacting resin systems and to determine the effect of gelation time on interfacial shear properties. To do this work, we developed a processing

Thermally Induced Stress Relaxation and Densification of Spin-on-Glass Thin Films

January 1, 2000
Author(s)
C. K. Chiang, William E. Wallace, G W. Lynn, D Feiler, W. Xia
The stress-temperature relationship of silica spin-on-glass thin films on silicon wafers was studied. Upon heating the stress-temperature curves showed a dramatically increasing slope when the temperature of the film was greater than 340 C. At 450 C, a
