Depth profiles of poly(vinyl chloride) (PVC) films chemically modified in solvent/non‐solvent mixtures were obtained using confocal Raman microscopy (CRM). The non‐destructive technique allows the characterization of interphases of up to 50 microns in thickness with a resolution of 1.4 μm. The accuracy of CRM is demonstrated by comparison of mean degrees of modification calculated from depth profiles and values obtained by transmission FTIR spectroscopy.
