Method & Evidence

AimTo investigate the effect of monomer ratios and process parameters on the synthesis of unsaturated polyesters and subsequently on the properties of multi-vesiculated particles (MVPs).
MethodDesign of Experiments (DoE) coupled with analytical characterization and microscopy.
ProcedureUnsaturated polyesters were synthesized using varying maleic anhydride (MA), phthalic anhydride (PA), and propylene glycol (PG) mole ratios, alongside controlled heating rates, agitation speeds, exotherm rates, and maximum processing temperatures. Design of Experiments software was used to optimize the experimental matrix. Synthesized polyesters were characterized using techniques like viscometry, titration, NMR, SEC, FTIR, and DSC. The resulting polyesters were then used to produce MVPs, which were analyzed for particle size and degree of vesiculation using SEM. Attempts were made to assess MVP hardness using AFM and microhardness testing.
ContextMaterials science and polymer synthesis for particle fabrication.
