<P>Chemo‐enzymatic methods are powerful tools for the synthesis of novel materials. By combining the flexibility of chemical synthesis and the high selectivity of enzymes, a variety of functional materials can be achieved. In the present study, a series of α,ω‐thiol telechelic oligoesters with varying amount of internal alkenes are prepared using selective lipase catalysis and are subsequently cross‐linked by thiol‐ene chemistry yielding alkene functional networks. Due to the reactivity of thiols and alkenes almost all present thiol‐ene systems consist of two components. This work demonstrates that selective lipase catalysis in combination with renewable monomers with internal alkenes is a promising system for achieving one‐component thiol‐alkene functional resins with good storage stability and a high degree of thiol end‐groups. The developed chemo‐enzymatic route yields polymer networks with tailored amount of alkene functionalities in the final thermoset, which facilitate further postmodification.</P>
