【摘要】 以四氢糠醇(THFA)、氢氧化钠(NaOH)和氯代正己烷(NHC)为原料合成四氢糠醇己基醚(THE),并对其作为结构调节剂在阴离子聚合物合成中的应用进行研究。结果表明:在THFA/NaOH物质的量比为(2.5～3.0)/1、NaOH/NHC物质的量比为1/(1～1.05)、类似酯化的反应温度为125～140℃和反应时间为5～5.5 h、取代反应温度为20～40℃和反应时间为2 h的条件下,NHC转化率大于98%,THE收率大于95%,提纯后THE质量分数大于0.99;THE分别在溶聚丁苯橡胶、氢化苯乙烯-丁二烯-苯乙烯嵌段共聚物和高乙烯基聚丁二烯橡胶的合成中用作结构调节剂,3种聚合物的乙烯基质量分数可有效控制在0.35～0.78。更多还原

【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.更多还原
