Abstract

The present invention relates to a method for preparing a rubber composition, which includes polymerizing glycerol monomethacrylate, crosslinking poly(glycerol monomethacrylate) obtained by boric acid to form a poly(glycerol monomethacrylate)-dynamic boronic acid ester complex, and compounding the complex with an additive. The present invention further relates to a rubber composition, a cured rubber composition, and a self-healing tire using the rubber composition.
