A set of copoly(ester amide)s ( s ‐PEAST n ) containing equal amounts of amide and ester groups has been synthesized from succinic and tartaric acids, and aliphatic linear amino alcohols with 2, 3 and 6 carbon atoms. In these mixed poly(ester amide)s the amino alcohol unit adopts a syndioregic orientation and the succinic and tartaric units alternate regularly along the polymer chain. These compounds were characterized by elemental analysis, SEC and FT‐IR and 1 H/ 13 C NMR spectroscopy. s ‐PEAST n are stereoregular polymers which display optical activity in solution and are crystalline in the solid state with melting points between 90 and 160°C. They all are non‐water soluble at room temperature but take up water in amounts up to 30% of their weights when exposed to a humid atmosphere.
