Title:
METHOD FOR PRODUCING MODIFIED CONJUGATED DIENE RUBBER
Document Type and Number:
WIPO Patent Application WO/2014/104169
Kind Code:
A1
Abstract:
Provided is a method for producing a modified conjugated diene rubber which comprises a step of reacting a compound represented by general formula (I) with an active terminal of a polymer obtained by polymerizing a monomer that contains at least a conjugated diene compound using, as a polymerization initiator, an alkali metal aromatic compound which has three or more carbon atoms directly bound to an alkali metal atom and an aromatic ring in one molecule.
(I)
(In the general formula (I), X is an atom or a reaction group that is capable of reacting with the active terminal of the polymer or a hydrocarbon group that includes either the atom or the reaction group, R1 to R4 are each independently a chemical single bond or an alkylene group having 1 to 10 carbon atoms, and R5 to R10 are each independently an alkyl group having 1 to 10 carbon atoms or an aryl group having 6 to 12 carbon atoms, wherein R5 to R10 may be bound together in a combination of R5 and R6, a combination of R7 and R8, or a combination of R9 and R10 to form a ring structure with a nitrogen atom.)
