Glass Transition Temperature Measurement of Elastomers

  • John J. Maurer


Analysis of the glass transition (Tg) process is a subject of wide and continuing interest both in the research and applied areas of polymer chemistry. (1–4) The advent of commercially available, high sensitivity DTA equipment has made it possible to easily undertake research in this area, and also to perform certain types of measurements which are not possible by other methods commonly used in Tg studies. This investigation was undertaken to examine critically the type of data about the Tg process which is obtained by DTA. Also of interest is the interpretation of certain characteristics of this process which appear in the DTA thermogram. This latter objective is attempted by comparison of the DTA data with those from linear expansion measurements. Throughout this work, attention was focused on polymers which, because of their elastomeric nature, have very low values of Tg.
