Calculation Tutorial:

STEP1: Enter the 'Enthalpy of Melting (ΔHm) for the polymer, which is the Area of the melting curve divided by sample weight obtained from DSC and its unit is J/g.

STEP2: Enter the 'Enthalpy of Crystallization (ΔHc) for the polymer, which is the Area of the Crystallization curve divided by sample weight obtained from DSC and its unit is J/g.

STEP3: Enter the 'Melting Enthalpy for 100% Crystallinity(ΔH*m) for the polymer, which is the value of Melting Enthalpy when the polymer is 100% crystalline. This value you can easily get from references.
