Abstract
In this paper, authors describe on the results of some mechanical tests concerning the brittleness of unplasticized polyvinylchloride.
The size of specimens which were used in our experiment was of J.I.S.
Tensile test, slow bend test and charpy impact test for specimens with or without U-notch were carried out at room temperature and each low temperature above-60°C.
From the results of these experiments, the authors have found that, there are nearly equal tendencies, as compared to the properties of carbon steel, concerning the effects of temperature and loading velocity on the absorbed energy per unit volume and transition temperature of this material.
