Abstract
Provided is a synthesis method of a modified conjugated diene polymer. Conjugated diene monomers are reacted in a reaction system. A modifier is added into the reaction system while the reaction proceeds to a predetermined extent. The modifier has a structure represented by formula (1): wherein R1-R11 each independently represent a C1-C5 alkyl group; 1≦m≦300; 0≦a≦65; 0≦b≦65; 0≦c≦40; 0<a+b; 0≦c/(a+b+c)≦0.8; the X and Y are structures respectively represented by formula (2) and formula (3): wherein R12, R16, and R17 each independently represent a C1-C5 alkylene group and R13-R15 each independently represent a C1-C5 alkyl group.
