<P>PROBLEM TO BE SOLVED: To provide an antiaging agent for rubber for improving the sustainability of the antiaging effect of a vulcanized rubber composition. <P>SOLUTION: The antiaging agent for rubber contains an antiaging substance for rubber and γ-cyclodextrin. The antiaging substance for rubber is preferably obtained by inclusion of the antiaging substance for rubber into γ-cyclodextrin. In solid-state NMR measurement, the chemical shift of a peak based on<SP POS="POST">13</SP>C of γ-cyclodextrin including the antiaging substance for rubber is preferably different from the chemical shift of a peak based on<SP POS="POST">13</SP>C of γ-cyclodextrin not including the antiaging substance for rubber. <P>COPYRIGHT: (C)2013,JPO&INPIT |
