TL;DR: In this article, the effects of electron beam irradiation on ten kinds of polymers containing various aromatic rings linked by functional groups in the main chain (aromatic polymer) were studied with reference to change in tensile properties.

TL;DR: In this article, the continuity and Poisson's simultaneous equations were solved to obtain the space charge profile and the field strength profile by solving the continuity equation and the Poisson equation.

TL;DR: In this article, the effect of radiation-induced oxidative irradiation on tensile properties of poly(aryl sulphones) was studied and it was concluded that deterioration in mechanical properties was brought about by chain scission only.

TL;DR: In this article, the dynamic mechanical relaxation of non-crystalline poly(aryl ether-ether-ketone) PEEK and the one irradiated with electron beam were studied and it was revealed from the study on the irradiation effects that three different molecular processes are overlapped in γ relaxation peak, i.e., molecular motion of water bound to main chain (peak temperature; at −100°C), local motion of main chain, and local mode of the aligned and/or oriented moiety (at −40°C).

TL;DR: In this paper, the effects of electron beam irradiation on molecular motions were studied by measuring dynamic viscoelastic properties in the temperature range from − 160°C to 350°C.
