Rubber compositions comprising a minor amount of natural rubber and a significant proportion of at least one synthetic triblock rubbery polymer and optionally a second synthetic rubbery polymer exhibit improved green strength and are useful in the fabrication of composite rubber articles, such as tires, hoses, belts, electrical products, toys, rollers, and the like. Specific examples of useful synthetic polymers include SBS triblock polymers and SBR copolymers. |
