Separation of the glass transition and postcuring (TOPEM®) - METTLER TOLEDO

Separation of the glass transition and postcuring (TOPEM®)

To demonstrate how TOPEM® (a temperature-modulated DSC method) can separate different effects and so allow the determination of the glass transition temperature, Tg, and the postcuring enthalpy, Δhpost.
A postcuring reaction usually begins just above the glass transition. In conventional DSCmeasurements, this often makes it difficult or even impossible to determine the glass transition temperature and the postcuring enthalpy.
