摘要： Bimodal high density polyethylene compositions can achieve an improved balance of stress crack resistance and processability by selecting the higher molecular weight and lower molecular weight components such that (1) the lower molecular weight component has a relatively high complementary density, which is a calculated property shown by the formula below, and (2) the higher molecular weight component of the composition has a moderately-low density and narrow molecular weight distribution. This combination of properties provides improved balance of stress crack resistance and processability without having to modify the properties of the higher molecular weight component.
