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
