摘      要：The gel and sol parts in epoxidized natural rubber(ENR) were separated with toluene and 2-pentanone, respectively, and their thermal aging behaviour were studied by FTIR spectrometry. The results indicate that the carbon-carbon double bonds and the epoxy bonds in both gel and sol are destroyed successively on aging process, accompanied with the occurance of the hydroxyl, ether, carbonyl of aldehyde and ketone groups. Along with prolonging the aging time, the aldehyde and ketone are further converted into ester structures. These changes of the functional groups demonstrate the gel is less thermostable than sol in ENR.
