Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

open access: yesPolymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐
