摘要
It is proposed that the environmental stress cracking of polyethylene is caused by stress-induced swelling and plasticization of certain favourably oriented amorphous regions in polyethylene. The criteria for stress-induced swelling together with the criteria for little swelling at zero stress show that a vigorous stress cracking agent will have a solubility parameter close to that of polyethylene and a large molar volume. Some detergents fit into this category. © 1978.
