Abstract
Disclosed is a rubber composition containing main-chain benzoxazine, in which benzoxazine generates no harmful materials during vulcanization and can thus be used in lieu of a phenol novolac resin used as a resin component of a conventional rubber composition, and also in which the use of benzoxazine, especially main-chain benzoxazine having a high molecular weight, is capable of maintaining excellent mechanical properties and exhibiting high flexibility. The rubber composition of the invention can be utilized for a rubber product, especially a tire product.
