A simultaneous determination method was developed for 89 polymer additives including 34 plasticizers in polyvinyl chloride. The samples were prepared by means of a published procedure for determination of antioxidants, ultraviolet stabilizers and lubricants in polyethylene. Additives were extracted with a mixed solution of cyclohexane and 2-propanol (1:1) by soaking overnight at 37°C, oligomers were removed by concentration and redissolution in warm acetonitrile, then analyzed by using GC/MS and HPLC. The recoveries of 34 plasticizers spiked in polyvinyl chloride were between 69.3-119.5% and the limits of quantitation were 50-500μg/g in polyvinyl chloride. Nonylphenol and bisphenol A could also be analyzed by this method.
