Zusammenfassung:	PROBLEM TO BE SOLVED: To carry out a qualitative analysis or a quantitative analysis of additives contained in a polymeric material easily, rapidly and accurately. SOLUTION: In the method, near infrared light with a wavelength being varied its absorption and reflectivity by the difference of the additives contained in the polymeric material is used in the measurement, and data of an infrared spectrum containing information relating to the difference of the additives is obtained, and then a data analyzing method in chemometrics which is easy to analyze data using a computer, is applied on the data of the infrared spectrum, and the information relating to the difference of the additives contained in the polymeric material is extracted from the data of the infrared spectrum, and thereby identifying the difference or the amount of the additives contained in the polymeric material based on the information obtained by the data analyzing method.
