摘要：

Samples underwent preliminary plastic deformation in the glassy state as a means of enhancing the accuracy of dilatometric determinations of T//g and of other temperature transitions relating to free volume changes occurring in samples. For PMMA it was found that the temperature coefficient of reduction in linear dimensions of a sample subjected to preliminary deformation shows a marked rise at T//g. Significant changes occurring in the linear dimensions of this sample during annealing make it possible to measure its elongation with the aid of an ordinary micrometer.
