Polyorthoester IV


POE IV is a modification of POE II which is formed of the diketene acetal with a diol which is modified by short sequences of polyglycolide or polylactide.

Performance Properties

POE IV is well known for surface-eroding properties and present unique opportunities for controlled-release and tissue-engineering applications.

Allows control over erosion rates without the need to add acidic excipients

POE IV stable and stored under anhydrous conditions
