The present invention relates to an interfacial polymer for a network used as a coupling agent in rubber-silica blend, and more particularly, to a block copolymer including a copolymer made of a conjugated diene and a vinyl aromatic monomer, which is a synthetic rubber and an inorganic silica. When used as a coupling agent, the silica dispersibility in rubber improves compatibility and processability, which greatly improves the mechanical and dynamic properties of rubber, thereby improving the braking performance and reducing rolling resistance when applied to tires. It relates to an interfacial polymer for rubber-silica networks. |
