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. |
