PURPOSE: To obtain an adherent rubber composition readily bondable to a thermoplastic resin or an elastomer without a primer, an adhesive or pretreatment such as halogenation.
CONSTITUTION: This adherent rubber composition is obtained by blending a raw material rubber with a thermoplastic resin or an elastomer compatible with the rubber, adding compounding agents, masticating and crosslinking. The thermoplastic resin or the elastomer almost homogeneously dispersed in the rubber can easily adhere to the same thermoplastic resin, a compatible thermoplastic resin or an elastomer through a process of melting or dissolving. Therefore, the obtained rubber product is readily bondable to the thermoplastic or the elastomer without a primer, an adhesive or pretreatment such as halogenation.
