Biocompatible polymer for fixing biological ligands.

摘要

biocompatible polymer, a molar mass greater than 50,000 g / mol, preferentially, 90,000 g / mol, allowing the fixing of biological ligands, which comprises at least a first linear segment having a more molar between 10,000 and 250,000 g / mol consisting of a hydrophobic homopolymer resulting from the polymerization of a hydrophobic monomer a; a second linear segment having a greater than 40,000 g / mol molecular weight and a preferably, greater than 80,000 g / mol consisting of a hydrophilic copolymer resulting from the copolymerization of a monomer B bearing a reactive function X , and a hydrophilic monomer C, and not carrying reactive any function, being linked, said second segment, one end of the first segment, a covalently, and constituting the set of the two segments, the polymer backbone .
