Disclosed are a rubber polymer including a unit structure derived from a conjugated diene-based monomer and at least one of compounds represented by Chemical Formula 1 to Chemical Formula 4, a method of preparing the same, and a rubber composition including the same.

Rubber polymer, method for preparing thereof, and rubber composition comprising the same

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.
