Patent ID: 8178641

Claim:
A method for producing an amino group-containing conjugated diene polymer comprising polymerizing a conjugated diene compound in the presence of a reaction product (a) of a compound shown by the following general formula (1) and a compound shown by the following general formula: RLi, in which R represents an alkyl group having 1 to 16 carbon atoms or an aryl group having 6 to 20 carbon atoms, to obtain a conjugated diene polymer, and reacting the conjugated diene polymer with a compound (b) shown by the following general formula (2) or (3), wherein R 1 represents a hydrogen atom or an alkyl group having 1 to 16 carbon atoms, wherein R 2 and R 3 individually represent a hydrogen atom, an aralkyl group having 7 to 20 carbon atoms, or an organosiloxy group, and R 4 represents a hydrogen atom, a trialkylsilyl group having 3 to 18 carbon atoms, an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or an organosiloxy group, wherein R 5 and R 6 individually represent an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, or an organosiloxy group, X represents an alkoxy group having 1 to 20 carbon atoms, an allyloxy group having 6 to 20 carbon atoms, or a halogen atom, R 7 represents a methylene group, an alkylene group having 2 to 20 carbon atoms, or an alkylidene group having 2 to 20 carbon atoms, and R 8 and R 9 individually represent a trialkylsilyl group having 3 to 18 carbon atoms when R 8 and R 9 do not bond to each other, or bond to each other to form a cyclic structure that is formed by the nitrogen atom that is bonded to R 8 and R 9 , two silicon atoms, and 1 to 10 carbon atoms.
