Near-IR (near-IR) spectroscopy can be used as a simple and effective method of qual. identification.We collected near-IR transmittance spectra of 30 different polymer samples for recycling identification.Both com. available blends and stock samples provided as monomer were analyzed, and each polymer was found to exhibit a unique spectral signature in the 1100-2500-nm region.Detailed qual. band assignments of each spectral feature were not necessary to identify the polymer being analyzed -- the relatively distinct absorptions in the C-H and C-C combination region could easily be used for identification purposes.This article shows that various complicated identification procedures, while useful, are not required for the qual. identification of polymers.
