Abstract

Dynamic mechanical properties of blends of waste polyethylene and virgin high density as well as low density polyethylene have been investigated before and after exposure to electron beam irradiation. Effect of radiation dose on the loss modulus, storage modulus, and damping factor of the blends has been reported. An increase in relaxation temperatures on exposure to radiation has been observed. Peak broadening has also been observed on exposure to radiation. The storage modulus and loss modulus of the blends increase, while that of tan δ decreases on irradiation.
