Abstract
Methods for controlled synthesis and chemical recycling of stereoregular polysaccharides via polymerization of biomass-derived anhydrosugars are provided. The anhydrosugars react with an initiator in the presence of a synergy of a catalyst and the initiator providing the polysaccharides with high chain end fidelity and an excellent molecular weight distribution in a controlled manner, which allows for the preparation of polymeric systems with well-defined architectures. The polysaccharides obtained by such methods can be substantially converted to the start monomers in the present of a catalyst and can be used for biomedicine.
