This research include new series of polymers were synthesized starting from polymerization of poly maleic anhydride (2), which were mono esterfication with absolute methanol to give polymer (3 ), then the acid side chlorinated with thionyl chloride to give polymer (4) , which was subjected to esterfication with protected sugar moiety (1) to afford modified polymer (5). Furthermore the hydrazide polymer ( 6) were prepared through addition of hydrazine hydrate to polymer (5), which upon condensation with different free mono saccharide to give the target polymer (7). The prepared polymers identified by spectral methods (FT-IR, 1H-NMR,13C-NMR) and some of its physical properties
