Abstract

The present work provides a new, well characterized hydroxyl functionalized biocompatible and degradable polymer that could be suitable for many different biomedical applications. Poly(2-hydroxyethyl methacrylate) (PHEMA) is a widely used and researched biocompatible polymer, but lacks degradability. In this work, degradable and less toxic PHEMA with ester linkages in the backbone could be successfully made by radical copolymerization with cyclic ketene acetal. The protection–deprotection chemistry at the hydroxyl group of HEMA was necessary for the formation of targeted polymers. The structure of the resulting polymers was unambiguously proved by 2D NMR techniques. The polymers were significantly less toxic with cell viabilities of more than 80% even for very high polymer concentrations (100 mg mL−1). The polymers were hydrolytically degradable under basic conditions and also showed surface and bulk degradation using macrophages. We also demonstrated promising positive results for the use of such polymers as sustained drug delivery systems.

  • Increasing interest in biodegradable polyesters and the versatility of RROP with respect to structures accessible via different monomers and their copolymerization with conventional vinyl monomers has changed the situation significantly.

    “However, with the increasing interest in biodegradable polyesters and the versatility of RROP with respect to the structures accessible via very different monomers [25] and their copolymerization with conventional vinyl monomers [26 -34] has changed the situation significantly.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
