Abstract

Abstract: Hyperbranched poly(β-cyclodextrin) was successfully prepared via hydrosilylation from AB_x type cyclodextrin monomer. The molecular structures of AB_x monomer and hyperbranched polymer were characterized with ¹H NMR, ¹³C NMR, ²⁹Si NMR, MALDI-TOF MS and elemental analysis. In addition, molecular weight, molecular weight distribution(MWD) and intrinsic viscosity of hyperbranched polymer were obtained via size exclusion chromatography/multi-angle laser light scattering(SEC/MALLS) technology.

Key words: AB_x type cyclodextrin monomer, Hyperbranched polymer, Hyperbranched poly(β-cyclodextrin), Hydrosilylation
