CO2-Based Polycarbonates with Low Glass Transition Temperatures Sourced from Long-Chain Terpenes

Philipp Holzmüller,
Christina Gardiner,
Jasmin Preis
et al.

Abstract: The urgent demand for more sustainable materials has led to significant research in the field of CO2-based polymers. This work describes monomer synthesis, polymerization, and polymer properties of long chain terpenoid- and CO2-based polycarbonates. Utilizing (R,R)-(salcy)-Co(III)Cl (Co(Salen)Cl) and bis(triphenylphosphine)iminium chloride ([PPN]Cl) as a binary catalytic system, high molar mass polymers (up to 46.4 kg mol–1) were achieved with narrow dispersities (M w/M n < 1.13) via solvent-free bulk polymeri… Show more

“…In the realm of natural products, terpenes represent a particularly interesting class of molecules for polymer chemists due to the presence of conjugated double bonds that offer both the opportunity to further functionalization or to directly polymerize these molecules in analogy to 1,3-alkadienes such as butadiene or isoprene. As a matter of fact, the stereoregular polymerization of acyclic terpenes has been investigated by using many catalytic systems, giving macromolecules various microstructural features and in some cases physical properties analogous to those of elastomers based on nonrenewable monomers. It is worth noting that, with a few exceptions, due to the long alkyl chain of the starting monomers such as myrcene, ocimene, and farnesene, even the highly stereoregular polymers do not show any crystallinity, limiting the possible application of polymers derived from terpenes.…”
