A protein polymer is soluble in aqueous media and retains the native ligand binding properties of the protein. The polymer comprises two or more protein monomer units, such as albumin molecules, that are covalently bound through coupling agents that give rise to spacer chains of atoms between the protein molecules. The spacer chains preferably have a length of at least twenty atoms. The protein polymers are suitable for pharmaceutical drug delivery of physiologically active molecules by a variety of routes.
