The functionalisation of limonene has enabled the synthesis of two renewably-sourced monomers for the formation of terpene-derived polyesters. Three methods for the synthesis of the novel hydroxy-acid 6 are reported and their green-credentials scruti... Read More about New renewably-sourced polyesters from limonene-derived monomers.

Sustainable synthesis and precise characterisation of bio-based star polycaprolactone synthesised with a metal catalyst and with lipase (2018)

Bio-based building blocks and sustainable synthesis pathways were used to synthesise star-shaped polymers composed of a D-sorbitol core and polycaprolactone arms by ring opening polymerisation (ROP). The use of volatile organic solvents was avoided a...

Journal of Supercritical Fluids, 139, 38-44. https://doi.org/10.1016/j.supflu.2018.05.003

We investigate the clean synthesis of a cross-linked poly(acrylic acid) viscosity modifier using supercritical CO2 to replace more hazardous volatile organic solvents that are typically used for this process. The polymers were analysed by aqueous swe... Read More about Synthesis and control of crosslinked poly(acrylic acid) based viscosity modifiers using dense phase carbon dioxide as a solvent.
