Residual 1,3-butadiene in poly(acrylonitrile-co-butadiene-co-styrene) (ABS) was extracted by solvent and using direct thermal desorption. Toluene and N,N-dimethylacetamide were used as the extraction solvents. The extracted 1,3-butadiene was injected by headspace sampling to analyze using GC. The solvent extraction was found to be more efficient than the direct thermal desorption method. Solvent extraction with toluene was more efficient than that with N,N-dimethylacetamide. Calibration curves of the 1,3-butadiene in toluene and N,N-dimethylacetamide showed good linear relationships. For the same concentration of 1,3-butadiene, the peak area of 1,3-butadiene in N,N-dimethylacetamide was larger than that in toluene. The experimental results were explained with the vapor pressure in the headspace and the compatibility of 1,3-butadiene with the solvent.
