Abstract: The present invention relates to polyphosphazenes, polyurethanes based on these polyphosphazenes, methods for their manufacture and hydrogels based on the polyurethanes. The invention further relates to the use of the hydrogels in medical, veterinary and agricultural applications. The terminal ends of the polyphosphazenes bear NCO-reactive hydrogen atoms for reaction with polyisocyanates.
