Abstract

This review summarizes some recent results which demonstrate the susceptibility of glassy polymerdiluent mixtures to exhibit a cavitational mode of plasticity at high stresses and strains in a temperature range close to Tg. The initiation of this mechanism results in extensive stress-whitening of the material. Most of the experiments have been conducted on mixtures of polycarbonate with esters of the phthalic acid. Deformation of these systems produces zones (crazes) of a very regular fibrillar microstructure which was then analyzed quantitatively by small-angle X-ray scattering. The microstructure is found to be largely different from that of the conventional type of craze. On the other hand, crazing of the mixtures of polycarbonate with the esters of the phthalic acid has the same characteristics as crazing II reviewed in a previous volume of this series (Adv. Polym. Sci. Vol. 52/53).
