Abstract
Unsaturated glucopyranose derivatives such as 1,2,3,4‐tetra‐O‐acetyl‐6‐desoxy‐β‐D‐xylo‐hex‐5‐enopyranose (3) and 1,2,3,4‐tetra‐O‐benzoyl‐6‐desoxy‐β‐D‐xylo‐hex‐5‐enopyranose (6), briefly called “Ac‐exo‐glucal (3)” and “Bz‐exo‐glucal (6)”, were synthesized. These exo‐cyclic sugar vinyl ethers were investigated in polymerization reactions. The corresponding “saccharide polymers”, homo‐ and copolymers, were synthesized under free radical conditions. The structures and the compositions of the soluble “saccharide polymers” were established by elemental analysis, ^1^H and ^13^C NMR, and FTIR spectroscopy. Characterization of the polymers, like molecular weights and optical rotations are reported. Saccharide polymers with different sugar content and low as well as high molecular weights were obtained.

## Abstract New “saccharide polymers” were synthesized. For this purpose the synthesis and the polymerization of an unsaturated sugar monomer, methyl 5‐deoxy‐2,3‐O‐isopropylidene‐ß‐D‐erythro‐pent‐4‐enofuranoside, briefly called “exo‐ribene”, is described. All polymers, homo‐and co‐polymers, were sy
