Abstract
Slow crack growth was measured in three polyethylene copolymers by a n otch tensile test at 50-degrees-C in Igepal Co-630. The concentration of Igepal was varied from 0 to 100%. The largest reduction in time to failure occurred in the concentration range between 0% and 0.1%. From 0.1 to 20% concentration, the additional effect was much less. A minim um in time to failure occurred at approximately 50% concentration. The re is a significant increase in failure time when the concentration is increased from 50 to 100%. If the failure time is < 10(3) min in air, Igepal has practically no effect.
