New renewably-sourced polyesters from limonene-derived monomers (2018)
Journal Article

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.

Clean Block Copolymer Microparticles from Supercritical CO 2 : Universal Templates for the Facile and Scalable Fabrication of Hierarchical Mesostructured Metal Oxides (2018)
Journal Article

© 2018 American Chemical Society. Metal oxide microparticles with well-defined internal mesostructures are promising materials for a variety of different applications, but practical routes to such materials that allow the constituent structural leng...

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

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...

A facile route to bespoke macro- and mesoporous block copolymer microparticles (2018)
Journal Article

We report a facile and versatile strategy for the bespoke fabrication of macro- and mesoporous block copolymer microparticles. A clean synthetic route, RAFT dispersion polymerisation in supercritical carbon dioxide (scCO2), is used to generate block...

Synthesis and control of crosslinked poly(acrylic acid) based viscosity modifiers using dense phase carbon dioxide as a solvent (2018)
Journal Article

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.
