| Abstract：Tetrahydrofurfuryl alcohol hexyl ether （THE） was synthesized from tetrahydrofurfuryl
alcohol（THFA），sodium hydroxide（NaOH） and n-hexane chloride（NHC），and its application as a structural
regulator in the anionic polymerization was studied. The results showed that when the molar ratio of THFA/
NaOH was （2.5 ～ 3.0）/1，the molar ratio of NaOH/NHC was 1/（1～ 1.05），the esterification reaction
was carried out at the temperature of 125～140 ℃ for 5～5.5 h，the substitution reaction was carried out at
20～40 ℃ for 2 h，the conversion of NHC was more than 98%，the yield of THE was more than 95%，and the
mass fraction of the purified THE was more than 0. 99. THE was used as a structural modifier in the synthesis
of solution polymerized styrene butadiene rubber，hydrogenated styrene-butadiene-styrene block copolymer
and high vinyl polybutadiene rubber respectively. The vinyl content of the three polymers could be effectively
controlled within 0.35～0.78. |
