A RUBBER COMPOSITION COMPRISING A BLOCK-COPOLYMER AND BLOCK-COPOLYMER

A rubber composition is disclosed comprising an elastomer, a filler, and a block-copolymer comprising an elastomer block and a thermoplastic block comprising a poly alkylacrylate. The poly alkylacrylate contains a single bonded oxygen atom. The alkylacrylate comprises a polycyclic substituent at its single bonded oxygen atom. The rubber composition may be used in an article of manufacture selected from a tire, a power transmission belt, a hose, a track, an air sleeve, and a conveyor belt. Also, a block-copolymer is disclosed comprising an elastomer block, and a thermoplastic block comprising a poly alkylacrylate. The poly alkylacrylate contains a single bonded oxygen atom. The alkylacrylate comprises a polycyclic substituent at its single bonded oxygen atom. The block-copolymer is a diblock copolymer.
