  • POLYURETHANES BASED ON SIDE CHAIN DIOL- AND DIAMINOPOLYPHOSPHAZENES AND THEIR HYDROGELS
    Publication number: 20230227600
    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.

  • Polymer for tissue engineering
    Patent number: 10815340
    Abstract: The invention relates to a polymer for tissue engineering from biodegradable polyphosphazenes, having photopolymerizable side groups, wherein the side groups of the polyphosphazenes are formed exclusively from amino acids and/or amino acid derivatives, which are bonded to the backbone of the polyphosphazene via the amino group of the amino acid and to a spacer attached to the acid group with a carbon chain of length m, which has a vinyl group at the free end, wherein m=0 to m=10.
    Type: Grant
