Proving Reliability and Reproducibility of the Technology for Grafting and Crosslinking Blends Based on Ethylene Vinyl Acetate Copolymer and Triallyl Cyanurate by Electron Beam Irradiation, Using Statistical Analysis of Experimental Data Obtained

The paper presents our experiments regarding the demonstration of reliability and reproducibility of the technology for grafting and crosslinking blends of ethylene vinyl acetate copolymer (EVA) and triallyl cyanurate polyfunctional monomer (TAC) by electron beam irradiation (EB). Blends based on EVA and TAC were irradiated with different doses of EB. The physical-mechanical properties of the irradiated samples were compared with those of samples obtained by classic crosslinking in the presence of peroxides. Experimental data obtained were processed and statistical analysis was performed using SPSS version 13 and regression models were established. Depending on the dose of irradiation, characteristics of the blends were estimated with a probability of 95% based on established regression models. The results have shown that the technology is reproducible and reliable.
