The Synthetic Polymers: Structure and Properties Research Group (PSEP)Open in a new window works on the synthesis and study of the structure and properties of new polymers, particularly biodegradable polymers. Its research focuses on techniques for monitoring hydrolytic, enzymatic and thermal degradation processes, studying their application as drug dosing systems (preparing microparticles, incorporating the active ingredient and monitoring their release).

Materials are characterised using standard spectroscopic techniques and their thermal and mechanical properties are determined. The properties of polymer materials depend on how the macromolecules are organised. The research group therefore also studies amorphous and crystalline phases. Crystalline structures are determined by combining powder or fibre X-ray diffraction, electron microscopy and molecular simulation techniques. Resolution is also performed using direct methods and single-crystal diffraction of model molecules that correspond to representative segments of the polymer sequence. The group also studies aspects related to kinetics (crystallisation and polymerisation) and crystal growth (from a molten state or dilute solutions).

The group is currently working on the design of polymers for specific applications and on the development of new biodegradable polymers for use as commodities, biocompatible polymers for surgical sutures, polymers for controlled drug delivery, glycolide polymers for biomedical applications, new biodegradable polyamides and polyester amides that contain natural amino acids, and biodegradable polyesters. It is also involved in studying the crystalline structure of synthetic polymers and model composites, determining mechanical properties and the effect of additives, using chain extenders to improve mechanical properties and preparing microparticles and polymer nanocomposites.
