The thermal and mechanical properties of a series of novel glycopolymer brushes with various degrees of polymerization of the backbone and various grafting densities are established. Modulated differential scanning calorimetry (MDSC) is found to be an effective tool for the characterization of the thermal behavior of these glycopolymer brushes. There is little difference among the glass transition temperatures of the different glycopolymer brushes. The elastic features of each glycopolymer predominate ( G ′ > G ″) at low frequency, while at higher frequencies the G ″ curve overtakes the G ′ curve, indicating the predominance of the viscous response.
