Abstract:
A modified conjugated diene copolymer and a preparing method for the same are provided. The method comprising a polymerization step for polymerizing conjugated diene monomers to form a conjugated diene polymer; and a modifying step for reacting the conjugated diene polymer with a modifier to form a modified conjugated diene polymer. The modifier includes a polythiol ester compound, a polythiol alkane compound or a combination thereof, the polythiol ester compound has a chemical formula (I): Ra-(O—C(═O)Rb-SH)x (I). The polythiol alkane compound has a chemical formula (II): HS—(CH2)m—(Rd)nCH2SH (II).
