A method is disclosed for preparing water soluble protein polymer conjugates which stabilize the protein so as to retain functional properties in a hostile environment. The method comprises covalently bonding the polymer to the protein through at least three linkers which linkers have three or more hydroxyl groups. The protein is conjugated at lysines or arginines.
