New monomers for thiol-yne based photopolymers were synthesized and characterized. It could be successfully shown that these building blocks provide significant lower cytotoxicity than the corresponding (meth)acrylates and offer comparably high reactivities. Network and mechanical properties of derived polymers were studied by dynamic mechanical thermal analysis (DMA) and low-field solid-state NMR. It turned out that monomers containing rigid backbones lead to moduli and glass transition temperatures, sufficiently high for the fabrication of medical devices.
