Unsaturated fructopyranose derivatives like 2,6‐anhydro‐3,4,5‐tri‐ O ‐benzoyl‐1‐desoxy‐β‐ D ‐ arabino ‐ hex‐1‐enopyranose ( 3 ) and 2,6‐anhydro‐3,4,5‐tri‐ O ‐acetyl‐1‐desoxy‐β‐ D ‐ arabino ‐hex‐1‐enopyranose ( 6 ), briefly called “Bz‐ exo ‐fructal” ( 3 ) and “Ac‐ exo ‐fructal” ( 6 ), were synthesised. These sugar monomers, which are exo ‐cyclic vinyl ethers, were investigated in polymerisation reactions. The corresponding “saccharide polymers”, homo‐ and copolymers, were synthesised under free radical conditions. The structure and composition of the “saccharide polymers” were determined by elemental analysis, 1 H and 13 C NMR, and FT‐IR spectroscopy. Characterisation and properties of the various polymers in terms of molecular weight, optical rotation, and glass transition temperature are reported.
