Abstract

A study was performed on the absolute specific heat capacity of poly(α-methyl styrene) and mixtures with its pentamer. It was found that the heat capacity was independent of concentration at temperatures from 240 to 480 K. Extrapolation to 100% polymer yielded the equilibrium specific heat capacity for the polymer at temperatures as much as 130 K below the Kauzmann temperature or 180 K below the glass temperature.
