The present disclosure relates to a modified conjugated diene-based polymer having excellent affinity with a filler, a method for preparing the same, a rubber composition including the same and a tire manufactured using the rubber composition. The modified conjugated diene-based polymer according thereto has a tin-based compound-derived group bind on one end, and a silane-based compound-derived group bind on the other end, and therefore, may have excellent affinity with a carbon black-based filler as well as a silica-based filler. Accordingly, a rubber composition including the modified conjugated diene-based polymer may have excellent processability, and as a result, processed goods (for example, tires) manufactured using the rubber composition may have excellent tensile strength, wear resistance and viscoelastic property.

A resin composition is disclosed. The resin composition may include a polybutadiene having an unsaturated bond in at least one selected from among a main chain and a side chain, at least one photoinitiator, at least one monofunctional (meth)acrylate monomer, and/or at least one (meth)acrylate oligomer. The resin composition may not include a urethane (meth)acrylate-terminated polybutadiene. An amount of the polybutadiene may be about 1 wt % or more and less than about 10 wt % based on a total of 100 wt % of the resin composition. The resin composition may have a shear viscosity of about 8 mPa.Math.s to about 50 mPa.Math.s as measured at a temperature of about 25 C. The resin composition may have a tensile modulus of about 10 MPa to about 900 MPa at a temperature of about 25 C. after photocuring.
