Polyurethane prepared from tetramethylene glycol and diisocyanate was exposed in the form of films to small pressures of NO 2 and to NO 2 plus air. Tensile strength was measured as a function of exposure time and temperature with an apparatus especially constructed for the purpose of measuring mechanical properties in different environmental “atmospheres.”
