Notes:
The kinetics of alcohol assisted, relaxation controlled craze growth in polycarbonate (PC) were studied between 280 to 340K in methanol, ethanol, propanol, butanol, and pentanol. Viscous deformation of plasticized craze material controlled the growth rate of a single craze during stress relaxation in single edge notched (SEN) specimens. The activation energy increased with craze driving force in all alcohols, except methanol, because of diffusion limited plasticization. The craze stress increased with the alcohol's ability to plasticize; this is not understood, but may be due to solvent Induced crystallization.
