    Water-soluble biodegradable polymers

    Polyphosphoester (PPE) polymers represent a new class of polymers that have attracted a lot of attention due to their water-soluble and biodegradable properties, which makes them the perfect candidates for nanotechnologies, in particular in the field of biomedicine. PPEs are synthesized by anionic ring-opening polymerization (AROP), which leads to a great control over molecular weights and dispersity. Further, it allows versatile modification of the polymer chains, in order to achieve different polymer architectures. The pentavalent phosphorus atom enables a high level of structural and chemical versatility. In addition, it is possible to fundamentally control the chemical and physical properties of the polymer, whereby properties such as water solubility and degradability can be adjusted as required.
