The non-isothermal crystallization of poly(ε-caprolactone)(PCL) samples with different molecular weight was studied by FT-infrared spectrometry. The non-isothermal crystallization parameters of PCL were obtained by quantitative analysis on the characteristic bands. The crystallization rate and the initiation temperature of crystallization increased with increase in the molecular weight of PCL. The non-isothermal crystallization parameters obtained by FTIR were consistent with those obtained by DSC.
