functional groups for covalent anchoring to biomaterials. We have developed an approach for a rapid synthesis of fucoidan-mimetic glycopolymer chains through cyanoxyl-mediatedfree-radicalpolymerization, a method suitable for chain-end functionalizing and subsequent linkage to biomaterials. The resulting sulfated and nonsulfated methacrylamido α-l-fucoside glycopolymers’ fucoidan-mimetic properties were studied
