Introduction

Where ΔCp and ΔCp pure are the changes in specific heat at the glass transition temperature, Tg, for the composite, and for the unfilled polymer, respectively. This work suggests an alternative method for determining Cp that takes advantage of fast heating and cooling rates to obtain quantitative Cp in the upper temperature region without having to dwell in that high temperature region to establish an upper isothermal.
