Une solution macromoleculaire devient birefringente sous l'influence des ondes ultrasonores. Nous avons developpe la theorie de l'effet pour le modele de la pelote statistique penetrable et a l'immobilisation partielle du solvent. La birefringence es

Studies of single-crystal deformation explain the small- and wide-angle x-ray observations of the cold drawing of PE, particularly the effects in the necking zone where the original spherulitic structure is transformed into a highly aligned fiber str

Exact treatment of intrinsic viscosity and streaming birefringence is possible for the limiting case of zero gradient where the coil dimensions are not yet perturbed by the flow. Experimental data on streaming birefringence in solvents of low viscosi

Density, heat of fusion and melting temperature data of annealed polyethylene single crystals suggest the existence of a temperature-dependent pseudo-amorphous surface layer which contains chain folds and free chain ends. In the ideal two-phase model

The gradient dependence of intrinsic viscosity and streaming birefringence is a function of the orientation and deformation of the randomly coiled macromolecule in the viscous force field of the laminar flow. Orientation decreases the contribution of

Electron diffraction and microscopy have been used to investigate the fine structure of fibrils pulled from deformed polyethylene and polyoxymethylene crystals. Since on annealing close to the melting point the striations developed transverse to the

Light-scattering data from solvent-exchanged, highly swollen gel cellophane were compared with the scattering theory for a three-component system (crystalline fraction, amorphous fraction, and imbibition liquid) originally developed for the scatterin

Under uniaxial tensile load, the plastic deformation of unoriented crystalline polymers first transforms the lamellae into a fibrous structure. Usually the drawing is inhomogeneous with a neck propagating through the sample. The higher the draw ratio
