Therefore, we reasoned that HPOX containing
both aliphatic and aromatic peroxalate ester linkages is able to
scavenge H2O2 and completely degrades because aromatic peroxalate
ester linkages in the polymer backbone react with H2O2,
leading to the cleavage of the polymer backbone and the release of
HBA. As demonstrated in the SEM image, HPOX we developed with
0.8 equivalent of cyclohexanedimethanol and 0.2 equivalent of HBA
was hydrophobic enough to formulate into nanoparticles under
aqueous conditions.
