Crazing on stretching of samples of high density polyethylene of different molecular mass in liquid media

Abstract

The effect of MM on the strain of high density polyethylene (HDPE) in liquid media is studied. It is established that the effectiveness of the action of the liquid media, as evaluated from the value of the decrease in yield point of the polymer, is inversely related to the MM of the HDPE. This effect is determined by the decrease in the liability of the crystalline polymer to undergo crazing in liquid media with increase in MM.
