Biodegradable polyesters derivedfrom hydrophobic amino acids are synthesized by various techniques, resulting in a wide range of molecular weights. The polymers are prepared via a) direct condensation with p‐toluenesulfonic acid (PTSA) as catalyst, b) ring‐opening polymerization (ROP) of O‐carboxyanhydrides, and c) ROP of cyclic dilactones. The polymers obtained by the first method reach a molecular
