ABSTRACT:
A method for producing an ester of a protein by an esterification reaction of an aqueous solution, fine powder or suspension of a protein having free carboxyl groups with an excess amount of polyfunctional alcohol to esterify the protein; a method for producing a protein-synthetic polymer conjugate from said ester by utilizing a hydroxyl or unsaturated group of a polyfunctional alcohol present in the esterified portion of the protein; and a protein-synthetic polymer conjugate produced thereby.
