<jats:title>Abstract</jats:title><jats:p><jats:bold>Summary:</jats:bold> A transfer function of the <jats:italic>RC1e</jats:italic>™ (<jats:italic>Mettler‐Toledo</jats:italic>) calorimeter was obtained by calibration with a heating cartridge. With this function it was possible to determine the heat flow rate and total heat of different polymerization reactions. The calorimeter operates in isothermal as well as in isoperibolic mode. Additionally, 1‐vinyl‐2‐pyrrolidone and acrylic acid were polymerized in a three‐neck flask. In this common laboratory device the heat flow rate was obtained by using a transfer function calculated by calibration with a heating cartridge. Thus, the heat of polymerization can be obtained without using a calorimeter and without solving the heat balance equation.</jats:p>
