Crystal Transformation, Piezoelectricity, and Ferroelectric Polarization Reversal in Poly(Vinylidentive proportional counter) X-ray system. Simultaneous X-ray and stress-strain relationship measurements during a drawing procedure revealed that the crystal transformation from Form II to Form I always initiates at the deformation stage where a necking was completed at the center of tensile samples,

Crystal Nucleation in Flowing Polymer Melts,of special interest to the field of polymer processing. This is because virtually all of today’s processing methods involve flow of a polymer melt either prior to or during solidification. Since flow is such an integral part of commercial processing, it is important to understand the effect which it

,Hydrostatic Extrusion of Glass Reinforced and Unreinforced Celcon® POM,ng, drawing and hydrostatic extrusion can impart substantial molecular orientation, consequently enhancing physical properties. Of these techniques, hydrostatic extrusion may have advantages in that glass filled resins may be employed and more complex profiles may be produced, including hollow secti

Transmission Electron Microscope Studies of Polymers Stained with Ruthenium and Osmium Tetroxide,orphology. The considerable microstruc-tural detail that can be brought out by the stain is exemplified by electron micrographs of thin films of incompatible blends of polystyrene with poly(methylmethacrylate). Crazes in strained solution-cast thin films of these polymer blends and in a strained sol

The Time-Temperature-Transformation (TTT) State Diagram and Its Role in Determining Structure/Propeered (i.e., liquid, rubber, ungelled glass and gelled glass) are related to the time and temperature of cure. Gelation and vitrification, as a consequence of quenching morphological development and chemical conversion respectively, are discussed with respect to control of material properties.
