We report the synthesis of novel terpene-based monomers: nopinyl acrylate and methacrylate, from naturally abundant β-pinene. A very high Tg value was observed for poly(nopinyl methacrylate) when synthesized by free radical polymerization, and well-defined polymers have been produced via RAFT polymerization This exciting new high Tg material shows promise as a hard block in thermoplastic elastomers. ABA triblock copolymers have been synthesized which also incorporate a low Tg renewable soft block, poly(tetrahydrogeraniol methacrylate), using a divergent, difunctional RAFT polymerization method. Initial phase separation behavior and adhesive properties have been investigated to highlight the potential of these copolymer materials as renewably sourced thermoplastic elastomers. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Application of 106-21-8).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application of 106-21-8
