## Abstract The synthesis of novel hyperbranched carbohydrate polymers, prepared by the ringβopening multibranching polymerizations of anhydro and dianhydro sugars, is described. The hyperbranched carbohydrate polymers were formed by the cationic polymerization of 1,6βanhydroβ__Ξ²__βDβhexopyranose,
Three new 1,4-anhydro-glucopyranose derivatives having different hydroxyl protective groups such as 1,4-anhydro-2,3,6-tri-O-methyl-a-D-glucopyranose (AMGLU), 1,4-anhydro-6-O-benzyl-2,3-di-O-methyl-a-D-glucopyranose (A6BMG), and 1,4-anhydro-2,3-di-O-methyl-6-O-trityl-a-D-glucopyranose (A6TMG) were sy
