[en] A chemically modified form of dextran was prepared; having a polymerizable moiety (acrylamide) and a reactive functional group (primary amine). Dextran was activated with 4-nitrophenylchloroformate (24 mol per polysaccharide, 9,8 mol per 100 glucose residues); 9,8% glucose residues were converted to aliphatic carbonates and 5,2% were converted to cyclic carbonates. The activated dextran was coupled with trityldiaminoethane (8 mol per 100 glucose residues), reactivated with 4-nitrophenylchloroformate, then coupled with acryloamidodiaminohexane (6,8 mol per 100 glucose residues). The trityl group was removed by hydrolysis with trifluoroacetic acid to yield the required aminated acryloamidodextran. The modified dextran was shown to be polymerizable by inverse emulsion polymerization. Submicron particules were successfully prepared, containing functional amine groups suitable for preparing drug conjugates or for modifying the surface properties of thisbiomaterial.
