| Abstract: | Aliphatic polyesters of controlled molecular weight and low molecular weight distribution were prepared via anionic ring-opening polymerization using a multifunctional star-shaped initiator. Functionalization results in star-shaped functional polyesters bearing methacrylate end groups. Novel biodegradable polyester resins were prepared by photochemical crosslinking of the functional polyesters. Three-dimensional microstructuring via UV replica molding shows the potential of this material as substrate for biomedical devices. |
