Application
(3S,6S)-(-)-3,6-Diisopropyl-1,4-dioxane-2,5-dione is a biodegradable monomer. As a diisopropyl substituted analogue of lactide, the resulting polymers feature reduced glass transition temperatures in comparison to polylactides of similar molecular weights. In addition to affecting the thermal properties, the isopropyl substitution increases the hydrophobicity of the polymer which corresponds to an increased degradation time.

Biodegradable polyesters derived from 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
