With growing concerns for the environment, there is an ongoing effort to develop sustainable polymers using materials derived from renewable feedstocks. Glycopolymers are examples of sustainable polymers, as the monomers can be obtained from saccharides. They retain excellent water solubility and, at the same time, have the additional benefit of controlled polymerization and enhanced thermal stability. In this study, we explore the synthesis of glycopolymer-containing block copolymers and their bulk self-assembly behavior. We first prepare glycomonomers by direct coupling of glucose to acrylate group. The glycopolymers are polymerized via the reversible addition-fragmentation chain transfer (RAFT) polymerization, followed by the sequential polymerization of polystyrene (PS) to yield glycopolymer-b-PS block copolymers. The thermal properties of the block copolymers are examined by differential scanning calorimetry, and the bulk morphologies are examined by small-angle X-ray scattering.
