Isoprene and β‐myrcene were polymerized by anionic polymerization in bulk and in the ‘green’ ether solvents cyclopentyl methyl ether and 2‐methyltetrahydrofuran and, for comparison, in cyclohexane and tetrahydrofuran. The polydienes produced in bulk and in cyclohexane contained high amounts of 1,4 units (>90%) whereas those produced in ether solvents were rich in 1,2 and 3,4 units (36%–86%). Comparison of the microstructures and glass transition temperatures of the polydienes obtained in the various solvents suggests that conventionally used solvents can be substituted by environmentally more friendly alternatives. © 2020 Society of Industrial Chemistry

在“绿色”溶剂中二烯的阴离子聚合

异戊二烯和β-月桂烯通过阴离子聚合反应在“绿色”醚溶剂中环戊基甲基醚和2-甲基四氢呋喃中进行聚合，而在环己烷和四氢呋喃中进行比较。散装和在环己烷中生产的聚二烯含有大量的1,4个单元（> 90％），而在乙醚溶剂中生产的聚二烯则富含1,2和3,4个单元（36％–86％）。在各种溶剂中获得的聚二烯的微观结构和玻璃化转变温度的比较表明，常规使用的溶剂可以用对环境更友好的替代品代替。©2020工业化学学会
