## Abstract Fourier transform infrared (FTIR) spectroscopy was used to reveal intermolecular interactions between carbon dioxide (CO~2~) and the carbonyl groups of poly(L‐lactide) (PLLA), poly(D,L‐lactide) (PDLLA), and poly(ε‐caprolactone) (PCL). After exposing polymer films to high pressure CO~2~,

✦ Synopsis
By employing Fourier transform infrared spectroscopy (FTIR) and curve±®tting techniques, the degree of crystallinity of poly(e e e e e e -caprolactone) (PCL) aged at room temperature for 1 month was estimated to be 49 AE 2 %. The degree of crystallinity determined by FTIR in this work is comparable with those found by other conventional techniques. It is suggested that the FTIR procedure established here for the crystallinity determination of PCL should also be suitable for the quantitative analysis of solid-state morphology of polymers containing carbonyl or other functional groups.
