Infrared Spectra of Polyvinyl Chloride

Polyvinyl chloride (PVC) is a synthetic thermoplasticpolymer with excellent water resistance, acid resistance, alkali resistance, electrical nonconductivity, and flame resistance, and is used in a wide variety of applications.Various types of additives such as plasticizers,stabilizers, and fillers can be added to this PVC resin,so that the final PVC product can be either rigid orsoft, depending on the amount of plasticizer added.Due to concerns about the adverse healthaffects of these phthalic ester plasticizers, includingtheir carcinogenicity, their application and contentlevels are regulated. Consequently, soft PVCcontaining various types of plasticizers instead ofthose containing phthalic esters are currently beingmarketed. Since soft PVC containing a large amountof plasticizer displays an infrared spectrum that isgreatly affected by the plasticizer, a variety of infraredspectral shapes are seen with soft PVC.Here we introduce and discuss the infrared spectra ofthis type of soft PVC.
