Abstract
The invention provides a method of synthesizing a copolymer of two .alpha.-amino acids which comprises the preparation of an N-carboxyanhydride of a first .alpha.-amino acid and the N-carboxyanhydride of a second .alpha.-amino acid, followed by the copolymerization of this mixture. The mixture is obtained by the reaction of phosgene with a mixture of a first and the second .alpha.-amino acids, the amino acids having similar reaction rates with phosgene. It also relates to the copolymer obtained by implementation of this method and an agent for covering skin wounds comprising this copolymer.
