Abstract
The present invention relates to an organic silica master batch elastomer prepared by mixing a conjugated diene based copolymer, a vinyl aromatic copolymer or a mixture thereof prepared by solution polymerization with organically modified silica in which the surface of silica is modified with a particular organosilicon compound and a silane coupling agent in solution. The resultant organic silica master batch elastomer exhibits improved mechanical properties, wear resistance and blending processability, and can provide the effect of extending durability of a tire.
