Abstract

Using the principle of tearing at a constant velocity and applying this to samples with longitudinal notches, a method of recording the tearing strength as a continuous function of temperature, crystallization time, and other factors which continuously vary the state of a (polymer) film material is developed. The characteristic points of the temperature transitions are determined for a number of polymer films in relation to their mechanical (strength) properties. The crystallization kinetics of polyethylene terephthalate films are analyzed.
