| This communication is concerned with the preparation of oligo(ε-caprolactone) (OCL)-modified polycyanurate (PCN) networks, and their subsequent use as precursors to porous thermosets. The polycyclotrimerization of dicyanate ester monomer in the presence of dihydroxy-telechelic OCL as a reactive modifier yields hybrid PCN/OCL-based networks. Starting from these systems, two straightforward routes can be envisioned to generate porous networks: the first approach implies a mere extraction of free OCL sub-chains, while the second strategy entails the selective hydrolysis of OCL fragments. The precursors as well as the resulting porous structures are characterized by several physico-chemical techniques, and the possibilities afforded by both routes are addressed. |
