摘要

PROBLEM TO BE SOLVED: To provide a rubber antioxidant agent comprising a rubber antioxidant substance.;SOLUTION: Provided is a rubber antioxidant agent in which a rubber antioxidant substance and a granular polymer are contained in a compatible state, and in which by "a rubber antioxidant substance and a granular polymer are contained in a compatible state" it is meant, in a solid NMR ¹H saturation recovery ¹³C-CPMAS method measurement, that the ¹H relaxation time of the rubber antioxidant substance contained in the rubber antioxidant agent is different from the ¹H relaxation time of the rubber antioxidant substance that is not in a compatible state with the granular polymer and that said relaxation time is approximately the same as the ¹H relaxation time of the granular polymer contained in the rubber antioxidant agent.;COPYRIGHT: (C)2015,JPO&INPIT
