The Influence of the Colloidal Structure of Polymer Blends on the Adhesion Strength of Polyolefin Compositions

The Effect of Addition EVA and LDPE-g-MAH on Irradiated LDPE Filled with Metal Hydroxides

“…Therefore, elongation at high temperature for compounds content ATH (1H-4H) were higher values than compounds with MH (5H-8H) at each irradiation (70-110 kGy). Table 2 reveals that addition of LDPE-g-MAH, as a compatibilizer, provided interactions at the surfaces of polymer matrices (1I-8I) and fillers [15] . Therefore, addition of high values of LDPE-g-MAH decreased HS% values at each irradiation (0-110 kGy).…”

“…Adhesion forces in compounds content ATH (1I-4I) were weaker than compounds with MH (5I-8I) [12][13][14][15][16][17][18] . Thus, TS values for compounds with MH (5I-8I) were higher than compounds content ATH at each irradiation and LDPE-g-MAH level.…”

“…Thus, increasing irradiation increased TS values of compounds (1J-8J) at each EVA level. EVA has conjugated bonds in its chemical structure, thus, it generates high free radicals at lower irradiation rate than LDPE [12][13][14][15] . Addition of EVA (40-100 phr) to the polymer compounds (1J-8J) provided a proper interaction between polymers-fillers and made higher cross-link bonds in polymer matrix at each irradiation.…”

“…Figure 15. Increasing irradiation produces high cross-link bonds in polymer matrices, decreases the internal chain mobility and prevents the polymers from becoming easily elongated [14][15][16][17][18][19][20] . Thus, increasing irradiation (0-110 kGy) decreased EB values of all samples (1J-8J) at each EVA content.…”

“…Figure 10 shows the TS values of compounds (1H-8H) versus irradiation (0-110 kGy and EVA levels (0-40 phr). Increasing irradiation produces and developes a threedimensional network inside polymer matrices [13][14][15][16] . Therefore, Increasing irradiation increased TS values of compounds at each EVA content.…”
