Local Molecular Motions in Bulk Polymers as Studied by Electron Spin Resonance (E.S.R.)r and the hyperfine A-tensor are introduced for atoms and molecules. Typical E.S.R. spectra obtained in solution and in oriented or nonoriented samples are given in the case of nitroxide radicals. The effects of molecular motions on line shape are given for fast and slow motions as well as the expre

Luminescence Polarization Methods for Studying Molecular Mobility and Orientation in Bulk Polymersboth mobility in isotropic systems and orientation in uniaxially symmetric systems. The particular case in which orientation and mobility simultaneously occur is examined. Typical examples of application of luminescence polarization in polymer field are indicated.

Chain Statistics of Amorphous Polymersscattering patterns..Part III considers the case when some multifunctional units are introduced, thus leading to branched polymers. When the degree of branching is sufficiently high, the statistics is no longer gaussian.

An Order-Disorder Theory of Stress Strain Behaviour of Glassy Polymersment with the external strain field and b.with θ. the angle between the i. segment and the applied field. Now M. is assumed to be a monotonic function of the applied strain, i.e. increasing the strain results in increasing order in the glass.
