A method of synthesizing a copolymer of two .alpha.-amino acids which comprises the preparation of an Ncarboxyanhydride of a first .alpha.-amino acid and the Ncarboxyanhydride of a second .alpha.-amino acid, followed by the copolymerization of this mixture. The mixture is obtained by the action of the phosgene on a mixture of a first and a second .alpha.-amino acids having close reaction rates with phosgene. The copolymer obtained by implementation of this method, and an agent for covering skin wounds comprising this copolymer, are also described.
