摘要
Identifying polymers, additives and contaminants presents unique challenges. Fourier transform infrared spectroscopy (FT-ER) coupled with spectral searching techniques is a very efficient and powerful methodology to answer most identification questions. It is based on the unique IR spectrum characteristic of each compound. This paper outlines procedures employed in the identification of typical PVC formulations, starting with the resin and proceeding to impact modifier, process aids, lubricants, stabilizer system and fillers. The emphasis is on FT-IR microscopy as the most versatile approach requiring small samples and minimal tone sample preparation. Other commonly used FT-IR techniques are also outlined. Wet separation protocols, applicability and limitations as related to FT-IR analysis are discussed. Typical examples include vinyl siding, packaging and bottle formulations as well as contaminants often encountered in these formulations and raw materials.
