Prediction method of life of polymeric material

摘要

PROBLEM TO BE SOLVED: To provide a life prediction method capable of predicting a life of a polymer material more accurately than a conventional life prediction method.SOLUTION: A life prediction method predicts a life of a polymer material by: irradiating a polymer material with a high luminance X-ray; measuring a carbon-carbon double bond amount by measuring an X-ray absorption amount while changing energy of the X-ray; and analyzing a degradation state of the polymer material from consumption of the carbon-carbon double bond of the polymer material when it is new.
