Tensile testing device for measurements on polymeric materials between −100 and +150°C. Mechanical behavior of cellulose in liquid media

摘要

AbstractA tensile testing device for measurements on polymer samples while immersed in a liquid is described. The temperature range is approximately −100 to +150°C. The sample older containing the immersion liquid is an all‐glass container attached to a modified tensile testing device. The thermostatting and recording equipment is also described. Stress–strain curves obtained with monofilaments of regenerated cellulose immersed inn‐pentane and liquid ammonia are shown. For filaments inn‐pentane the variation of the modulus of elasticity with temperature down to −40°C is also reported as a further example of the applicability of t
