摘要：
A metharylate monomer having an octanal-derived bicyclo bisoxazolidine (BBOX) moiety was synthesized and was radically copolymerized with a methacrylate having a hydrophilic poly(ethylene glycol) chain to obtain an amphiphilic copolymer having the BBOX moieties as hydrophobic side chains. The BBOX moieties were stable for 7 days at pH 7.0, whereas they were gradually hydrolyze at pH 5.0 to release octanal continuously for 7 days, confirming the potential applicability of the copolymer to a polymeric pro-fragrance that can release aldehyde-type fragrance molecules slowly for a long period.
