(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image) Well-defined amine ω-terminated [beta]-myrcene polymers were synthetized via anionic living polymerization under an inert atmosphere with dropwise addition of equimolar amounts of N-benzylidenetrimethylsilylamine to [beta]-myrcene polymer living chain ends in benzene at 25 °C. Chain coupling and acetophenone polymers were not detected as side products. End-group titration with perchloric acid showed a polymer amination yield of up to 85 % of ω-terminated [beta]-myrcene polymers. The amine ω-terminated [beta]-myrcene polymers were synthesized with a narrow molecular weight distribution (... [asymptotically =] 1.1) as calculated by GPC analysis using polystyrene standards. Functionalization of the amine group in the polymer chain was corroborated with FTIR, ^sup 1^H-NMR, and ^sup 13^C-RMN spectra. A higher yield of the amine ω-terminated [beta]-myrcene polymer was not achieved due to differences in isomer conformation in the [beta]-myrcene polymer.
