Abstract
This paper deals with the ethylene-propylene-terpolymer rubber (EPDM) crosslinking and grafting by use of accelerated electrons (AE) beams in the presence of a multipurpose monomer such as trimethylolpropane-trimethacrylate (TMPT). Physico-mechanical characteristics of the samples irradiated with various AE doses were compared with those of the sample obtained by classical crosslinking in the presence of peroxides. The resulting data were subjected to processing and statistical analysis to show the reliability of the EPDM crosslinking and grafting by means of AE. Based on the experimental data, the single factorial regression models for the assessment with a 95 % probability of rubber blend characteristics with different irradiation doses were established. Keywords: EPDM, crosslinking, radiations, regression model, estimation of variables
