Preparation of polymers containing sugar residues

The synthesis of five different polymers containing sugar residues on side chain is described. 1‐O‐Methacryloyltetra‐O‐acetyl‐D‐glucose, 1‐O‐methacryloyltetra‐O‐acetyl‐D‐galactose, and 6‐O‐methacryloyltetra‐O‐acetyl‐D‐glucose were prepared and polymerized. The polymethacrylates obtained were converted into water‐soluble polymers by removing the acetyl protective group with sodium methoxide. 6‐O‐Methacryloyldiisopropylidene‐D‐galactose was also prepared and polymerized. The isopropylidene protective group was removed by acid hydrolysis. Poly (N‐methacryloylglucosamine) was prepared directly by the polymerization of N‐methacryloyl‐D‐glucosamine without the use of any protective group.
