We have investigated certain physical and mechanical properties of polypropylene that had been crosslinked with various amounts of quinone in the presence of a fixed amount of 1,4-ditertbutyloperoxy diisopropyl benzene. To achieve this we have used s

The ultrasonic attenuation of PVCz in 1,2-dichloroethane solution was investigated as a function of temperature and frequency. The relaxation observed is assigned to segmental motions of the chain. The activation enthalpy of this process and the enth

The interface of metal-to-alumina ceramic seals was examined by an electron probe and by X-ray methods. The thickness of the interface was found to be 11 to 15 μm. About 75 w o of the interface was amorphous glassy phase and the remaining 25 w o was

Theoretical problems concerning the propagation of ultrasonic waves in a porous medium are outlined. The propagation velocity of longitudinal ultrasonic waves in an elastic medium with spherical gaseous inclusions is considered in detail. The calcula

Formulae describing the effective elastic moduli of a porous ceramic medium are derived using Eshelby's solution and Maxwell's approximation. The ceramic medium is considered as an infinite matrix, which has uniform elastic properties and encloses no

The results presented confirm the effect known from other works e.g. 4, that the electric strength of solid insulation decreases with the increase of its linear dimensions /size effect/. The application of a point electrode forced a breakdown to occu
