“…Typically, a-pinene is not employed in polymerizations, as it is signicantly less reactive than b-pinene; however, it can be hydrogenated, pyrolyzed, oxidized, and isomerized into b-pinene or mixtures of other terpenes and terpenoids, such as a-phellandrene, myrcene, and menthol. [120][121][122][123] b-Pinene, a-phellandrene, myrcene, and menthol are among pinene derivatives that have been studied in controlled polymerizations. [117][118][119][120] Myrcene-and menthol-based polymers and their potential as rubbery blocks are discussed throughout Section 3.2 whereas poly(b-pinene), poly(a-phellandrene), and their BPs are reviewed in this section.…”
