Abstract:

Compressive stress-strain curves of two different glasses of a polyurethane based elastomer have been obtained at 3 Kbar and -5.5 C as a function of ageing time. The glasses were formed by two different perturbation jumps of pressure and temperature. The shape and the size of the curves depended on the path and ageing time. Youngs modulus increased with ageing time and represents a good mechanical parameter for determining relaxation of polymer glasses. Keywords High pressure Elastomer Solithane 113 Glass relaxation Relaxation time Modulus of elasticity.
