We performed Langevin dynamics simulations of amphiphilic polymers that contain strongly associating stickers connected by long soluble chain segments. We explored the aging of a thermoreversible gel, which is cross-linked by aggregates (clusters) of the stickers, and observed a dramatic increase of their lifetime with aging. We find that the observed aging is the result of structural reorganization of the network: the number of cross-links decreases with time as small clusters disintegrate and their stickers are reabsorbed by large clusters that grow and become more stable by forming additional intramolecular associations between their stickers.
