Abstract

Biodegradable poly(1,5-dioxepan-2-one) (PDXO) was grown directly from Si-OH groups of a silica nanoparticle by surface-initiated, ring-opening polymerization (SI-ROP) of 1,5-dioxepan-2-one (DXO). The direct SI-ROP of DXO was achieved by heating a mixture of Sn(Oct)₂, DXO, and the silica nanoparticles (316 nm in diameter) in anhydrous toluene. The resulting silica/PDXO hybrid nanoparticles were characterized by means of ¹H NMR spectroscopy, IR spectroscopy, thermogravimetric analysis, and field-emission scanning electron microscopy.
