Abstract
The invention concerns a process for preparing saccharide monomers comprising at least one polymerizable acrylate or methacrylate group whereby the saccharide used in the process is selected from mono-, di- and tri-saccharides, in particular from non-reducing mono-, di- and tri-saccharides. The process comprises reacting the saccharide in an aqueous medium with an esterifying reagent containing the polymerizable acrylate or methacrylate group in the presence of a base while maintaining the pH of the reaction medium to a value within the range of 7 to 11 during the entire reaction time. The invention furthermore concerns saccharide monomers comprising at least one polymerizable acrylate or methacrylate group with a controlled degree of substitution.
