Abstract
This paper reports on the phenomenon of shattering of unreinforced PVC roof membranes. To further understand the problem and to provide data for the assessment of existing in-service unreinforced PVC roofs, samples of unshattered (unweathered) and shattered membranes were studied using dynamic mechanical analysis. It was found that the glass transition temperature, Tg, may be useful in explaining the shattering phenomenon. Furthermore, the Tg values can easily be obtained using dynamic mechanical analysis.
