(2020-23) - BSc (with Honours)

(2023-Current) - PhD in Polymer Chemistry (Haddleton Group)

Current Research

• Anionic polymerisation of functionality-controlled Hydroxy-Terminated Polybutadienes (HTPBs)
  • Synthesis of di/tri-functional organolithium initiators
• OH Functionality determination of HTPBs
• Curing of HTPBs with diisocyanates to form crosslinked polyurethane binders for use in rocket propellants
  • Modifying ratios of diisocyanates with HTPB and monitoring changes in molecular weight in flow via GPC
  • Measuring physical characteristics of cured polymers via DSC
  • Measuring rheological changes of curing polymers
• Effect of antioxidants on rheological and kinetic characterstics of cured HTPBs

Future Work

• Utilising flow chemistry to produce HTPBs and polyurethane binders in a time and cost efficient manner.
• Designing isocyanate-free crosslinking methods
