The polymerisable glucose derivates,6-O-vinyladipoyl-D-glucose was sythesized by chemoenzymatic transesterification,the novel thermosensitive glycopolymers,poly (N-isopropylacryamide-co-6-O-vinyladipoyl-D-glucose)(NIPAAm-co-OVAG) were fabricated free radical copolymerization from N-isopropylacryamide(NIPAAm) and 6-O-vinyladipoyl-D-glucose(OVAG). The structures and properties of the copolymers were confirmed by ¹H NMR,UV-Vis absorbance and GPC. Moreover,the hydrodynamic diameter and gyration radius of the poly(OVAG-co-NIPAAm) in aqueous solution were studied by laser light scattering. Finally,we found that the poly(OVAG-co-NIPAAm) chains exist in aqueous as nearly spherical nanoparticles with diameter around 60 nm and the lower critical solution temperature(LCST) increased from 32℃ of PNIPAAm homopolymer to 39℃.
- self-aggregation,
- thermosensitive glycopolymer,
- enzyme catalyzed synthesis,
- double-hydrophilicity
