- 摘要：
PROBLEM TO BE SOLVED: To provide a method for determining, evaluating, and testing a degree of deterioration or a life of resin material containing antioxidant in a relatively short period of time.
SOLUTION: The deterioration degree determination method of a resin material comprises the steps of: preparing a specimen of the resin material containing antioxidant; measuring a mass spectrum of the specimen by a gas chromatography/mass spectrometry; obtaining a peak area of a total ion chromatogram from the mass spectrum; obtaining concentration of the antioxidant, and decomposed matter and/or modified substance thereof (hereinafter, referred to as a measuring object) within the resin material from the peak area; and determining a deterioration degree of the resin material by comparing with a predetermined index, on the basis of the area.
