Novel Approaches to Glycopolymer Syntheses from the Viewpoint of Polymerization Chemistry

All articles of this category The new approaches to glycopolymer syntheses are introduced from the viewpoint of classification into the general polymerization reactions, i.e., polyaddition, polycondensation, and radical polymerization. The ring-opening polyaddition of sugar oxazoline monomers having the hydroxy group gave stereoregular aminopolysaccharides. Hydroxy-terminated oligodihexanoylchitin was prepared and its block copolyaddition with the other hydroxy terminated polymer or oligomer was carried out using diisocyanate as a coupling reagent. The direct polycondensation of d-glucosamine derivatives using the appropriate condensing agents proceeded at a primary hydroxy group of position 6 regioselectively. Furthermore, spontaneous polycondensation of aminosaccharide monomers gave new aminopolysaccharides having unique structures. Radical alternating copolymerization of 1,2-dideoxysaccharide with maleic anhydride took place using AIBN initiator. glycopolymer - saccharide monomer - polyaddition - polycondensation - radical polymerization
