| titleOfInvention | Method for producing dilithium initiator |
| abstract | PROBLEM TO BE SOLVED: To produce a dilithium initiator in a non-polar solvent without using a nitrogen- or oxygen-containing polar compound and use the obtained solution as it is in a polymerization reaction, When a polymer having a narrow molecular weight distribution is obtained and a conjugated diene is used as a monomer, a polymer having a small 1,2-bond structure in a conjugated diene polymer portion is obtained. SOLUTION: In a non-polar hydrocarbon solvent, a monoorganic lithium compound and 1,3-diisopropenylbenzene are mixed with 2 When a dilithium initiator is produced by reacting at a molar ratio of / 1, a π-complexed compound having a benzene ring is converted to a monoorganic lithium compound at a molar ratio of 1 to the monoorganic lithium compound. -10 to 1000/1, and -20 to 6 A production method in which the reaction is performed at a temperature of 0 ° C. |
