Abstract

The specific isobaric heat capacities of poly (methylmethacrylates) (PMMA) having various tacticities were measured by the DSC method within a broad range of temperatures including the glass transition. Glasses with uniform thermal history were used in the measurements and the data were treated by employing a procedure which provided the “thermodynamic” Tg independent of the experimental conditions. The semiquantitative validity of Boyer's empirical relationT g ×Δcp=const. was confirmed; also it was found that within the limits of experimental accuracy the cp,g values at 298 K andC p,l values at 400 K are independent of the tacticity of the sample.

Using the data thus measured and linearized equations representing the dependence ofT g on the content of iso-, syndio- and heterotriads, the Tg values of pure isotactic PMMA and pure syndiotactic PMMA were found to be respectively 315 K and 397 K.
