%X A new method for fast determining the K value of poly(vinyl chloride)by means of near infrared(NIR)spectroscopy was developed.Orthogonal signal correction method was introduced to model the quantitative correlation between the NIR spectroscopy and the K value of poly(vinyl chloride).The results show that the correlative coefficients and the standard error of prediction(RMSEP)between the chemical analysis value and the NIR predicated value of the K value of the sample were 0.9825 and 0.5933 after the orthogonal signal correction.The relative error of the predicted results was less than 0.5%.The experiment results show that better performance and simpler partial least square model can be achieved with the orthogonal signal correction algorithm than Partial Least Square and a new approach is provided for the fast measurement of the K value by NIR spectroscopy.
