Synthesis of Carboxyl Terminated Polymyrcene by Anionic Polymerization Using CO2 as a Terminating Agent

Journal of Polymer Science, EarlyView.
The anionic polymerization of myrcene and termination with carbon dioxide to produce carboxyl terminated chains were investigated. The highest degree of functionalization was obtained in the batch reactor by headspace addition of the CO2 to the unstirred reactor at −78°C.
