Abstrakt: 1',2,3,3',4,4',6-Hepta-O-benzyl-6'-N-methacryloyl-6'-deoxysucrose 1, 6'-deoxy-6'-N-methacryloyloxyethylureido sucrose 2 and 6,6'-dideoxy-6,6'-N-dimethacryloyloxyethylureido sucrose 3 have been homo-polymerized and copolymerized with styrene by a free radical process, yielding polymer materials with pendant sucrose moieties, attached to the polymer backbone via amide linkages. The results demonstrated that varying the structural features of the monomers, greatly affected the thermal and rheological properties of the polymers. The polymer materials obtained have been characterized by NMR, MALDI-TOF, DSC, AFM and EWC (equilibrium water content). The efficient synthesis of the three novel, regioisomerically pure, N-methacryloylamide sucrose-containing monomers (1, 2 and 3) have been described.
