On the basis of microhardness (H) data measured at room temperature only for a number of polymers in the glassy state, a linear correlation between H and the glass transition temperature T g has been found (H Ο 1.97T g Οͺ 571). By means of this relationship, the deviation of the H values from the add
The empirical form for the dependence, Tg(n) = Tg(co) (1 + a / n ) , of the glass transition temperature Tg on the average number n of repeat units between crosslinks, is generalized for randomly crosslinked high polymers. The new form, TJn) is based on a correlation study of data for 77 samples of
