Abstract
Disclosed is an interfacial polymer for a network used as a coupling agent in mixing of rubber-silica. More particularly, the interfacial polymer for a rubber-silica network is a block copolymer containing a copolymer of conjugated diene and vinyl aromatic monomers, in which when used as a coupling agent in the mixing of synthetic rubber and silica (an inorganic material), the polymer enhances silica dispersibility within the rubber, and improves compatibility and processability, resulting in considerable improvement in the dynamic property as well as the mechanical property of the rubber, and when used in a tire, etc., it enhances automobile braking performance and reduces rolling resistance.
