Embodiment 1
[0055] Under argon protection, 100ml of benzene and 900ml of n-hexane were first added to the polymerization reactor, and the initiator n-butyllithium was added according to the design molecular weight of 5kg / mol, and according to the formula of functionalized diphenylethylene derivative monomer / initiator The ratio is 1.0 and 1-[4-(N,N-trimethylsilylamino)phenyl]-1'-phenylethene is added to initiate the reaction for 10 minutes. The reaction solution in the polymerization reactor was heated to a polymerization temperature of 30° C., 10 g of isoprene was quickly added, and polymerization was initiated for 2 hours. Quickly add 0.5 g of styrene, 9.5 g of butadiene, and add tetramethylethylenediamine (TMEDA) according to the regulator / initiator ratio of 1.0 to continue polymerization for 2 h. Continue to add 24 g of styrene, 48 g of butadiene, and 8 g of isoprene, and polymerize for 2 h. Add the coupling agent SiCl according to the initiator / coupling agent ratio of 2.0 2 (CH3) 2...
Embodiment 2
[0057] Under the protection of argon, first add 100ml of benzene and 900ml of cyclohexane into the polymerization reactor, add the initiator sec-butyllithium according to the design molecular weight of 250kg / mol, according to the ratio of functionalized diphenylethylene monomer / initiator Add 1-[4-(N,N-methyltrimethylsilylamino)phenyl]-1'-phenylethylene to initiate the reaction for 30min at 1.0. The reaction liquid in the polymerization reactor was heated to a polymerization temperature of 70° C., 30 g of isoprene was quickly added, and polymerization was initiated for 1 hour. 13.5 g of styrene and 16.5 g of butadiene were quickly added, and tetramethylethylenediamine (TMEDA) was added to continue polymerization for 1 h according to the regulator / initiator ratio of 2.0. Continue to add 2 g of styrene, 30 g of isoprene, and 8 g of butadiene, and polymerize for 2 h. Add the coupling agent SnCl according to the initiator / coupling agent ratio of 2.0 2 (CH 3 ) 2 , Initiate the c...
Embodiment 3
[0059] Under argon protection, 100ml of benzene and 900ml of pentane are first added to the polymerization reactor, and the initiator sec-butyllithium is added according to the design molecular weight of 400kg / mol, and the ratio of functionalized diphenylethylene monomer / initiator is 1.0 Add 1-[4-(dimethylmethoxysilyl)phenyl]-1-[4-(N,N-dimethylamino)phenyl]ethylene, 1,1'-bis[4 -(N,N-Dimethylamino)phenyl]ethylene initiated the reaction for 10 minutes. The reaction solution in the polymerization reactor was heated to a polymerization temperature of 70° C., 20 g of isoprene was quickly added, and polymerization was initiated for 10 minutes. Quickly add 6 g of styrene, 14 g of butadiene, and add tetrahydrofuran (THF) according to the regulator / initiator ratio of 50 to continue polymerization for 30 min. Continue to add 6 g of styrene, 24 g of isoprene, and 30 g of butadiene, and polymerize for 1 h. Add coupling agent TiCl according to the initiator / coupling agent ratio of 2.0 2...
