Abstract
Irradiation can be applied to crosslink the dispersed elastomer phase to increase the modulus and decrease the voiding ability of the elasto mer, which results in increasing critical brittle-tough transition ela stomer content at constant temperature. The experimental results show that at 25 degrees C the critical elastomer content of EPDM shifts to higher composition (shift of about 4 wt%) for PBT/EPDM blends after 10 0 kGy gamma-irradiation.
