The interrelation between physical properties and the molecular structure of EPR has been the subject of extensive studies, and need not be reviewed here. Far less attention has been given to the effect of molecular structure on dielectric properties on nonpolar polymers such as polyolefins. Most published information refers generically to polymers without more detailed definition of the prevailing molecular peculiarities, such as crystallinity, molecular weight, density, or monomer contents, as in the case of copolymers. |
