Study on the Improvement of Physical-Mechanical Characteristics in the EVA/PVC Blends Irradiation with Electron Beam in the Presence of Triallylisocyanurate

The paper presents irradiation of thermoplastic elastomers based on ethylene-vinyl acetate (EVA) and poly(vinyl chloride) (PVC) plasticized with small ionizing radiation doses, in the presence of triallylisocyanurate (TAC), for the purpose of improving their characteristics. Results obtained from the study have shown that by irradiating blends of EVA/PVC in presence of TAC, new materials with improved properties have been obtained, as a result of crosslinking reactions and reorientation of sample particles under the influence of accelerated electrons. The optimal irradiation dose and the optimal TAC concentration can be chosen depending on the composition of each blend and on the applications of the final product.
