This application is a National Stage Application of International Application No. PCT/KR2013/000892, filed Feb. 4, 2013, and claims priority to and the benefit of Korean Patent Application No. 10-2012-0011617, filed on Feb. 6, 2012, and Korean Patent Application No. 10-2013-0011063, filed on Jan. 31, 2013, the disclosures of which are incorporated herein by reference in their entirety.
The present invention relates to a modified conjugated diene polymer and a method for preparing the same. The present invention relates to a modified conjugated diene polymer which exhibits superior compatibility with an inorganic filler, heat generation, tensile strength and abrasion resistance, low fuel consumption and excellent resistance on wet roads and a method for preparing the same.
Demands for stability, durability and low fuel consumption of vehicles are increasing. Accordingly, there is an increasing demand for rubbers exhibiting excellent resistance on wet roads and mechanical strength and low rolling resistance as materials for vehicle tires, in particular, tire treads contacting the road.
Hereinafter, the modified conjugated diene polymer, the method for preparing the same, the rubber composition comprising the modified conjugated diene polymer and the tire comprising the rubber composition will be described in detail.
The modified conjugated diene polymer according to the present invention comprises a polymer represented by the following Formula 1:
wherein R1 is an alkyl group or an alkylsilyl group, R2 is an alkyl group or alkylene group, R3 and R4 are an alkyl group, a is an integer of 1 to 3, 1 and k are an integer of 0 to 2, m is an integer of 1 to 3, l+k+m satisfy 3, p is a conjugated diene polymer chain, and b is an integer of 1 to 3, wherein two R1 bonded to nitrogen, when k is 2, may be identical or different, and similarly, corresponding groups, when l and m are 2 or more, may be identical or different.
