Abstract For compiirison with low density polyethylene, the effects of irradiation on the mechanical properties of high density poivethylene filaments were studied. With the vacuum-irradiation, the tensile strength decreased with dose for the unelongated and slightly elongated samples; it was practically constant for highly eiongated samples. On the other hand, the tensile strength of the air-irradiated samples decreased considerably with dose. Young's modulus and degree of elasticity at 65% RH and 20 deg C were insensitive to dose, just as those of the low density polyethylene. The per-cent shrinkage of the irradiated filaments decreiised with dose, and the flow point rose in vacuum irradiation but fell in air-irradiation. (auth)
