[0233]A 20 L capacity stainless polymerization reactor was washed, dried, flushed with dry nitrogen, and charged with 10.2 kg of hexane (specific gravity 0.68 g / cm3), 547 g of 1,3-butadiene, 173 g of styrene, 6.1 mL of tetrahydrofuran, and 5.0 mL of ethylene glycol diethyl ether. Subsequently, 10.5 mmol of bis(diethylamino)methylvinylsilane and 14.9 mmol of n-butyllithium were poured in as a cyclohexane solution and an n-hexane solution respectively, and polymerization was started.
[0234]Copolymerization of 1,3-butadiene and styrene was carried out while continuously supplying the monomers to the polymerization reactor at a stirring speed of 130 rpm and a polymerization reactor internal temperature of 65° C. The amount of 1,3-butadiene supplied during the entire polymerization was 821 g, and the amount of styrene supplied was 259 g.
[0235]Following this, the polymer solution thus obtained was stirred at a stirring speed of 130 rpm, 10.5 mmol of N-(3-dimethylaminopropyl)acrylamide was ...

[0238]A 20 L capacity stainless polymerization reactor was washed, dried, flushed with dry nitrogen, and charged with 10.2 kg of hexane (specific gravity 0.68 g / cm3), 547 g of 1,3-butadiene, 173 g of styrene, 6.1 mL of tetrahydrofuran, and 5.0 mL of ethylene glycol diethyl ether. Subsequently, 12.9 mmol of n-butyllithium was poured in as an n-hexane solution, and copolymerization of 1,3-butadiene and styrene was carried out for 0.83 hours. During polymerization, the stirring speed was 130 rpm, the polymerization reactor internal temperature was 65° C., and the monomers were supplied continuously to the polymerization reactor.
[0239]After the polymerization had been carried out for the 0.83 hours, 10.5 mmol of bis(diethylamino)methylvinylsilane was charged into the polymerization reactor as a cyclohexane solution under conditions of a stirring speed of 130 rpm and a polymerization reactor internal temperature of 65° C.
[0240]Subsequently, the monomers were continuously supplied to the ...

[0244]A 20 L capacity stainless polymerization reactor was washed, dried, flushed with dry nitrogen, and charged with 10.2 kg of hexane (specific gravity 0.68 g / cm3), 547 g of 1,3-butadiene, 173 g of styrene, 6.1 mL of tetrahydrofuran, and 5.0 mL of ethylene glycol diethyl ether. Subsequently, 10.5 mmol of bis(diethylamino)methylvinylsilane and 13.4 mmol of n-butyllithium were poured in as a cyclohexane solution and an n-hexane solution respectively, and copolymerization of 1,3-butadiene and styrene was carried out for 1 hour. During polymerization, the stirring speed was 130 rpm, the polymerization reactor internal temperature was 65° C., and the monomers were supplied continuously to the polymerization reactor.
[0245]After the polymerization had been carried out for the 1 hour, 10.5 mmol of bis(diethylamino)methylvinylsilane was charged into the polymerization reactor as a cyclohexane solution under conditions of a stirring speed of 130 rpm and a polymerization reactor internal tem...
