The method of quick qualitative and quantitative analysis of PVC matieral and PVC product by FTIR analysis and thermal-weight analysis was described in detail. For the unbeknown samples, the pyrolyzate is identified primarily by FTIR spectrometeric qualitative analysis, then the primary result is validated by that the solute is identified by FTIR spectrometeric qualitative analysis. The process of pyrolysis of PVC matieral is complicated. The content of components can’t be showed rightly by the sample curve of thermal-weight analysis. The content of PVC may be worked out by the result of thermal-weight detemination. There is good linear relationship in the rangs 30%-80% content of PVC(R=0.9983). The method is more quick and convenient than traditional methods with reliable result.
