AbstractThe tensile properties of bisphenol A polycarbonate films were measured as a function of temperature from +25 to −180°C. The tensile properties at a given temperature were determined from the measured true stress‐true strain behavior of the polycarbonate films by means of a photographic strain recording technique. The temperature dependence of the following tensile properties is presented: the yield stress, the fracture stress, the strain to yield, the cold‐drawing strain, the fracture strain, and the strain‐harden
