Abstract
Changes in the parameters of porous structure of the crazes produced b y cold drawing of PET in the presence of surface-active liquid environ ments was studied. Relaxation phenomena were shown to be accompanied b y dramatic structural rearrangements of the craze structure and take p lace during polymer loading. The intensity of relaxation phenomena was found to be controlled by the flexibility of craze fibrils and their interaction via coagulation contacts and the development of a network of physical entanglements.
